Can't this be summed up with making it super attractive for sellers (or the content creators) early on, grow really fast and then completely screw your content creators after you're somewhat established?
This is what it seems like for just about every marketplace. Marketplaces seem like one of the most corrupt / shady / backstabby lines of businesses I've ever been a part of. This is coming at it from a content creator on some video course platforms in the past.
