That's reassuring to know.
I would assume that security services can log everything even for VPN users. Plus, as Sakai observes, relying on technology for the security of revolutionaries is only part of the solution. The main risk comes from other people (who may appear to be comrades but are spies).
The state isn't the only one to be worried about, though. With reactionary politics sliding into open fascism more and more, there are ordinary members of the public who don't have access to the same powers as the state but who could get access to similar data if we're not careful.
One thing I've always wondered is whether using a VPN puts you in a list for trying to hide your internet activity. They're paranoid. I'm paranoid. It's the age of paranoia!
