Not sure he wants it. PocketBase is just a backend he developed for his main project, Presentator, and everything I’ve read from his conversations are “Yep, I’m publishing this because someone else might get some use out of it but I’m not developing by consensus here”, and I don’t think he wants it to be his full time job (he’s always super polite and helpful, not trying to imply he’s rude or dismissive or anything).
Obviously everyone has a price, so maybe I’m wrong, but even then you’ve not solved the “bus factor” problem.
