I have no idea what anyone should be doing, but I'll tell you what I personally am doing:
- emailing my representatives over and over
- emptied all cloud services and all personal big tech accounts (can't do much about the work ones..)
- getting acquainted with Linux, VPNs and Tor
- learning to flash custom ROMs
- testing said custom ROMs
- digging into app permissions - even graphene comes with things enabled that I realized I want to turn off (like ad privacy, printer services and android services that enable nearby share which I personally don't use)
- use Obtainium and F-droid for apps
- testing out p2p services to see which ones are useful
- stashing Linux isos, so I hopefully always have at least one that either doesn't have age verification or one where it's easy enough to rip out
- downloaded "linux from scratch", but I'll admit I haven't read it yet
