I generally agree with your reasoning, but recently experienced a counter-example myself. I recently picked up Joplin for note-taking, and the fact that it can sync reliably through my NextCloud instance via WebDAV was the deciding factor in me sticking with it. If I had to rely on a company to stick around to sync my notes, or I had to run a custom backend, I would have simply moved on. As is, Joplin is pretty close to an ideal note-taking system for me.
