i genuinely don’t understand why people ‘self-host.’
I self host an XMPP server for family and friends. No electron anywhere near it. It's tiny, will run on a potato. But it's ample for the 16-ish of us on the thing.
I do it because it let us avoid big tech surveilence IM services.
I also self host web pages. I am 100% sure they have no tracking pixels, no analytics scripts, no enshittification of any kind. The moment I use a commercial "build your web site with our super easy app!" thing, enshittification gets bundled right in behind the scenes.
