Yep, in that sense it's really not fair at all to compare it against traditional services that lock you in like Evernote/Notion/Roam.
I guess I can sympathise in the sense that I really wish org-mode was more widespread outside of Emacs. It feels like a real barrier for adoption (if you're trying to get into semantic org-mode features, not just merely using it for syntax). But I don't see what we can do about it for now.
