I hear what you guys are saying, but "maximize revenue/profits" means "benefit advertisers so they come to us instead of anybody else." "Getting a cut of all transactions" means benefitting advertisers who sell anything through the site.
What? Getting a cut of transactions has nothing to do with advertisers. Are you saying apple forcing app payments through the App Store is about advertisers? Seems like you are trying to fit all scenarios to a predetermined narrative here.
It's all advertising all the time.
