For privacy reasons, I've already started slowly switching away from US providers before all this insanity happened. I've switched my Email to Proton (Swiss), cloud files to Filen (German), most LLM usage to Mistral (French), and search to Ecosia (German). [Edit: I've now switched to Mojeek; see comments below.]
But in the past two weeks, I've done the things I've previously put off because they require real work. I've set up a NAS and switched all of the remaining things. I'm now using Immich for photo hosting, Vaultwarden for passwords, Hoarder for bookmarking, and a self-hosted Standard Notes instance for note-taking, to-do lists, and saving articles for later reading.
I'm super happy with this setup. Immich, in particular, is absolutely fantastic; its default face recognition model works better than Google Photos, at least for me. Once you've set it up, you can log your family into the same NAS and have them use it, too.
