Not OP, but I am self-hosting a bunch of things, like my blog. I am trying to move away from Google, my primary email for important things is under my domain (not purely self-hosted, but still). I am also creating backups so that I can recover if a service is gone for any reason.
Exactly, I've stopped worrying so much about what "everyone" is doing, and just continue to do my own thing. I've self-hosted E-mail and web for 15+ years at this point. I keep my music and movies on spinning metal in my garage with an NFS server running on it. Photos stored locally too, and everything backed up on my own storage. I don't care how locked-in Spotify keeps you, because I don't need Spotify. I don't care how much data Netflix collects, because I don't use it.
It's always fun to read articles about how urgently we need to go back to local-this and self-hosted that, knowing I never left!
So yea, some of us are practicing what we preach.
