Self hosting will always remain a hobby thing. Most people won’t give the time need to properly admin their own system and an improperly admined system is a risk that you don’t want to take with your precious data. I can’t blame people for not doing this - there are ball games to watch, saw dust to make, kids to raise, and millions of other things to do with your free time such that you cannot do everything you might want to. Sure most people could learn to do this, but it isn’t a good use of their time.
What the world needs is someone trustworthy and cheap enough to handle data for people who have better things to do. Which is why I have fastmail handle my email. I self host a lot of other things though because I don’t know of anyone I can trust to do a good job for a reasonable price.
Every few months I turn it on for a few days just to see if it is better.
Then I go back to the old AST based autocomplete that actually knows something useful about my code.
