In the wake of the recent (west)world-wide push for increased surveillance, I want to start a little discussion: what do you think would be the best way to insulate yourself from prying eyes at the OS level? [...] I'm only focusing on one machine directly exposed to the Internet here, [...]
Imma be real with you. Connecting a fully featured OS directly to the internet is suicide. All the services that are running even on something minimal are a huge attack surface and if you are "interesting" you're going to get fucked. At a minimum you need a device/router with a relatively secure, for-purpose OS (like pfsense), running a NAT that is dropping all incoming packets you didn't specifically ask for. This is also why IMO IPv6 is cancer.
That done (and I know this is trite but it is true) you should be asking what your threat model is. If you're just trying to browse anonymously the OS doesn't really matter so much as the browser. I would setup the tor browser with ublock and to not save history/cookies/etc. Just yeeting the tracking pixels and a cookie cleaner extension is like 90% of what you need.
If we're worried about advanced, personalized attacks then I think your outward facing router/device needs more attention. Running on something that doesn't have an IME/PSP. Auto-updates enabled. Fail2ban (not that you should have ssh from WAN enabled anyway). use dnscrypt, etc. Browsing from your actual PC with javascript disabled.
If you're worried about the government then it pains me to say this but depending on how mad they are they're probably going to get you anyway. Actual physical arrest, an intentional supply chain attack (or maybe you really do read and understand ALL the code on your machine perfectly?), or a 0-day aren't really stoppable. The trick is to not get to this point where they're big mad
and know who you are because at that point it's already ogre.
The thought. Is trannies are by far over represented in tech, and open source related jobs. So by their own logic.

"White people can't be discriminated against"
And so on and so forth.
