If you didn't realize the importance of privacy after the patriot act and seeing the continuation of right wing authoritarianism, it's definitely time to get on board asap. Get yourself and your community on signal instead of texts and tuta or proton instead of regular email, use a vpn (mullvad or proton are solid), and depending on what kinds of actions you may or may not be interested in, learn how to use tails os and tor (try to find a copy of the darknetmarket bible for a good intro)
Edit: simplex is a good alternative to signal too, and if you have a google pixel, grapheneos is solid. Next time you're getting a new phone, get a used pixel and install it. On your computer, there's a lot of telemetry and sketchy stuff windows does, either research and disable that or switch to linux if you can
