I disagree. I can't think of an implementation mistake that would allow just the government to see what services you sign up for.

You could of course screw it up so everybody could see. If the government put a keylogger on your device then they could see. However broadly speaking this is not something that can be screwed up in such a way that just the government would be able to see.

The protocol wouldn't even involve any communication with the government.
