This is all just an educated guess, but "Olivia" is an active member of the "YMS community" (if there is such a thing). If you pay attention to the live chats in the YMS streams you can tell that a lot of people know each other and that most of them are degenerate furries. "Olivia" also streams on his own channel. I don't know how many viewers he gets on average. I would assume those are the same people who donate to the YMS clips patreon, so i don't think most regular viewers really care 'cause they are all degenerate furries anyways. But i personally still think it is dumb if he wants to broaden his viewer base.
It was brought up here, some weeks ago, that Adam has been struggling financially and he was considering putting ads in his videos. Guess he finally pulled the trigger.
