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.
So yea, some of us are practicing what we preach.
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!
