For profit.  So to answer your question at the end, yes it will ironically be bad in the end if it works well enough.

If everyone uses the for profit app, I can't imagine that organization resisting the incentives & threats they'll be subjected to towards capture as the userbase reaches a critical mass.

The app would ideally use UX patterns to push people off to more sovereign options... but if they're profit driven, that's a nonstarter.  Even if they're altruistic, with enough threats, it's a nonstarter.  Legacy social media incentives.

I'd love to see it, just seems very unlikely to successfully do what we're looking for here.
