Privacy: Ross Ulbricht handed in his appeal to the U.S. Supreme Court last week, highlighting an important Analog Equivalent Privacy Right in the process: Just because you’re using equipment that makes a third party aware of your circumstances, does that really nullify any expectation of privacy?

In most constitutions, there’s a protection of privacy of some kind. In the European Charter of Human Rights, this is specified as having the right to private and family life, home, and correspondence. In the U.S. Constitution, it’s framed slightly differently, but with the same outcome: it’s a ban for the government to invade privacy without good cause (“unreasonable search and seizure”).

U.S. Courts have long held, that if you have voluntarily given up some part of your digitally-stored privacy to a third party, then you can no longer expect to have privacy in that area. When looking at analog equivalence for privacy rights, this doctrine is atrocious, and in order to understand just how atrocious, we need to go back to the dawn of the manual telephone switchboards.

At the beginning of the telephone age, switchboards were fully manual. When you requested a telephone call, a manual switchboard operator would manually connect the wire from your telephone to the wire of the receiver’s telephone, and crank a mechanism that would make that telephone ring. The operators could hear every call if they wanted and knew who had been talking to whom and when.

Did you give up your privacy to a third party when using this manual telephone service? Yes, arguably, you did. Under the digital doctrine applied now, phonecalls would have no privacy at all, under any circumstance. But as we know, phonecalls are private. In fact, the phonecall operators were oathsworn to never utter the smallest part of what they learned on the job about people’s private dealings — so seriously was privacy considered, even by the companies running the switchboards.

Interestingly enough, this “third-party surrender of privacy” doctrine seems to have appeared the moment the last switchboard operator left their job for today’s automated phone-circuit switches. This was as late as 1983, just at the dawn of digital consumer-level technology such as the Commodore 64.

This false equivalence alone should be sufficient to scuttle the doctrine of “voluntarily” surrendering privacy to a third party in the digital world, and therefore giving up expectation of privacy: the equivalence in the analog world was the direct opposite.

But there’s more to the analog equivalent of third-party-service privacy. Somewhere in this concept is the notion that you’re voluntarily choosing to give up your privacy, as an active informed act — in particular, an act that stands out of the ordinary, since the Constitutions of the world are very clear that the ordinary default case is that you have an expectation of privacy.

In other words, since people’s everyday lives are covered by expectations of privacy, there must be something outside of the ordinary that a government can claim gives it the right to take away somebody’s privacy. And this “outside the ordinary” has been that the people in question were carrying a cellphone, and so “voluntarily” gave up their right to privacy, as the cellphone gives away their location to the network operator by contacting cellphone towers.

But carrying a cellphone is expected behavior today. It is completely within the boundaries of “ordinary”. In terms of expectations, this doesn’t differ much from wearing jeans or a jacket. This leads us to the question; in the thought experiment that yesterday’s jeans manufacturers had been able to pinpoint your location, had it been reasonable for the government to argue that you give up any expectation of privacy when you’re wearing jeans?

No. No, of course it hadn’t.

It’s not like you’re carrying a wilderness tracking device for the express purpose of rescue services to find you during a dangerous hike. In such a circumstance, it could be argued that you’re voluntarily carrying a locator device. But not when carrying something that everybody is expected to carry — indeed, something that everybody must carry in order to even function in today’s society.

When the only alternative to having your Constitutionally-guaranteed privacy is exile from modern society, a government should have a really thin case. Especially when the analog equivalent — analog phone switchboards — was never fair game in any case.

People deserve Analog Equivalent Privacy Rights.

Until a government recognizes this and voluntarily surrenders a power it has taken itself, which isn’t something people should hold their breath over, privacy remains your own responsibility.

Pirate Parties: This past weekend, elections were held in Luxembourg and the Czech Republic. The Pirate Party of Luxembourg tripled their support and entered the Luxembourg Parliament with two MPs, and in the Czech Republic, the Pirate Party increased their support further – now receiving a full 17% in Prague.

With 6.45% of the votes of the final tally, the Luxembourg Pirate Party is entering its national Parliament, being the fifth Pirate Party to enter a national or supranational legislature (after Sweden, Germany, Iceland, and the Czech Republic). This may not seem like much, but it is a very big deal, for reasons I’ll elaborate on later. A big congratulations to Sven Clement and Marc Goergen, new Members of Parliament for Luxembourg!

Further, the Czech Republic has had municipal elections, and the Czech Pirate Party showed a full 17.1% support in Prague, the Czech capital, making the Pirates the second biggest party with a very narrow gap to the first place (at 17.9%). This may or may not translate to votes for the Czech national legislature, but is nevertheless the highest score recorded so far for a Pirate Party election day. I understand the Czech Pirates have as many as 275 (two hundred and seventy-five!) newly-elected members of city councils, up from 21 (twenty-one). Well done, well done indeed!

For people in a winner-takes-all system, like the UK or United States, this may sound like a mediocre result. In those countries, there are usually only two parties, and the loser with 49% of the vote gets nothing. However, most of Europe have so-called proportional systems, where 5% of the nationwide votes gives you 5% of the national legislation seats. In these systems, the parties elected to Parliament negotiate between themselves to find a ruling majority coalition of 51%+ of the seats, trying to negotiate common positions between parties that are reasonably close to each other in policy. This usually requires a few weeks of intense negotiations between the elections and the presentation of a successfully negotiated majority coalition.

Further, it could reasonable be asked what kind of difference the Czech Republic or Luxembourg could possibly make on their own in the global information repression. The answer is, a whole lot. The key here is realizing that one country is sufficient to break the global repression of information; the repression is completely dependent on every single country keeping watertight doors. If one single country decides to allow the free movement of culture and knowledge, then all such distribution will immediately be based there. The copyright industry lobby in other countries will protest, quite loudly, but there’s not really anything they can do about it.

And since the problem from a policymaking standpoint has been that the industry-age era politicians consider the Internet-related policy areas completely peripheral in the first place, conceding those policy areas will be seen as very cheap price to bind those votes to a majority coalition.

“One country is sufficient to break the global repression of information.”

A relevant comparison is how Canada has now legalized cannabis at the country level, following many state-level initiatives here and there in the world, and at once, the floodgates are open. Not just for the illegal distribution networks, but more importantly, for legalization everywhere else. As a German politician dryly said today, “what’s possible in Canada is also possible in Germany”, proposing that cannabis should be legalized outright in Germany. I would imagine the tone is similar in most places — or, importantly, many enough places.

The Luxembourg and Prague coalition talks have just started, with an outcome typically expected in a few weeks.
