You are quite polite in using the word "unethical" to describe such behavior and the situation in general. This is theft, pure and simple, and I'm very sorry to hear it.
Yes and unfortunately being polite isn't always good, at least not in situations like this.
Unfortunately, this is the sad and bitter truth. As long as Governments and their authorities want everyone to be monitored and controlled in every single action they take, anonymity is out of the picture.
The way I see it, it can go in one of the two following directions:
a. The company will try to be lawful and do everything according to the legislation, so the authorities will eventually force them to do all this crazy shit.
b. The company will cease to exist, like eXch did. I could also use the silkroad example, but let's not have this conversation about silkroad because it was a very ambiguous situation.
