You are indeed not a competitor for Patreon. The biggest problem people seem to have with Patreon is exactly this: every company creating its own definition of hate speech, which could result in their customers (creators) being cut off their income for things they say, even on other platforms. Which effectively creates censorship, and a growing administrative cost for all companies.
