0. pihole, firewall, filter non-marketing shit you don't want to read about.
1. ubo is ok, uMatrix is better. takes time though
2. Get rid of all the big players' software, Firefox is one of them
3. You need your own proxies. Tor is a must for a lot of things
4. when it comes to hardware, nothing established, best not to have bluetooth
devices when you are in cities or commuting on trains, buses and so on
5. the dumber the phone the better, always unbloat, be in control of automation and init systems, control what happens after restarts and updates.
6. don't use saas. never use saas. if you can, check out the data sets they collect.
7. have an air tight system for a diverse range of use cases, like re-installing stuff
8. obfuscation, not just your fingerprint but your entire life. have two or three. get some bots, let them run weird shit on your networks.
9. if your place and time and social circle allow it, build your own physical networks.
10. the byte streams relevant data can be packed into are really tiny,
your bluteooth, the connection to your cell tower, your m1 or snapdragon going brrr for a tiny fraction of time can tell whole stories
but that's waaaay too much to just keep the ads away. just don't look
