It used to be that if the US government wanted access to documents or letters in my possession they’d have to subpoena me directly. As a foreign citizen there are all sorts of ways I could fight the request – and it was at least my choice whether to do so. As someone living in the US I also had the whole weight of the 4th Amendment on my side. Now, with everything in the cloud, the decision whether to hand over my personal information is almost entirely out of my hands. And unless, as happened with Twitter, the company storing my data decides to fight for openness on my behalf, there’s every possibility that I won’t even hear about the request until it’s too late. That’s just not how things should work in a free society.
