Yeah I think Boba was just less open to it than she might’ve thought, which is completely understable. Posting cute pics to twitter and getting a confidence boost from compliments is a completely different scenario than getting sent dms on OF + she didn't like how it kept getting brought up in her streams.
If I am not mistaken, people had mentioned boba quit because it started "bleeding" too much into everything else. Her streams, twitter, instagram, etc, were getting more comments about people asking/talking about OF, and I guess the reality that she had dilluted her content must have sink in. She probably saw herself heading down a path where she was more of an onlyfans girl than a gaming youtuber/streamer.
I'm not so sure. Ose may be an independent network member but she's in a ton of the main channel content these days (and in practically every Duncan series apart from Minecraft) so I think if the Yogscast as a business entity really had that much of an issue with OF they wouldn't be putting pretty much the OG Yogs OF front and center so often. I really don't see that as the deciding factor for her not giving it another go.
It's very much a different kettle of fish for an employee to have an OF vs an independent contractor (essentially). Morality clauses are pretty standard (and I'd expect one after the Turps situation) and I would bet all the money in my pocket they're already seeing sponsors who request creators without OF/OF-like content, as that's what sponsors are doing pretty much everywhere.
From what I've gathered from previous years, Yogs at least spend very little time at the convention itself and it's mostly a company bonding trip/ networking at various partner parties.
