I'm just spitballing, but he's probably be lucky to retain 50% of his audience if he switched to only SubscribeStar. And that wouldn't be all at once either. They would trickle in slowly over months.

And, as we well know, only a fraction of the audience even pays attention on Patreon itself. That's just not a good way to rally your members, it would be financially devastating.
