Depends on your definition of "a lot of complaints".
He currently has 17391 Patrons. Under his latest Patreon post are 607 comments. Assuming every single one is a complaint from one single person without repetition, that's ~3,5% of Patrons. Let's be generous and add all comments from his last 5 posts (607+315+15(higher tier Patrons only)+248+73(Patrons only)), that's 1258 potential complainers. If every single one were a unique Patron, that would be ~7,3%.
In both cases over 90% of Patrons aren't complaining.
Just because the vocal part of the community is complaining, doesn't mean it represents the general Patreon population.
