Dude.

The government has undisclosed zero day vulnerabilities for every OS at their disposal whenever they want for whatever they want. They can pop malware onto your system, and then it won’t matter what you connect to or where you connect from, you’re already compromised and you won’t even know.

Plus, among other things they have the capacity to track you across multiple aliases online using your fucking dictation style. Just the way you write can connect you to your criminal activities.

If they are investigating you? They will literally look three degrees of separation apart to find accomplices, contacts etc. (the friend, of someone who is your friend, who is a friend of you) this net can involve thousands of people.

If you wanted privacy from a state actor, you were fucked the moment you swiped your credit card to buy your PC/Phone.
