Thank you, I did not know about Fairphone - I will give it a closer look. It looks interesting.

Honestly, sel-hosting email, DNS, etc. seems perhaps too “advanced” for me - I am not sure I would be able to do it without causing more problems than I solve.

I am resigned to the fact that I cannot be completely independent, protected from surveillance by any state, etc. At this point, I am just looking for ways to prevent catastrophic scenarios, such as Trump blocking (or threatening to block) Europeans' access to American clouds and the like.
