God, this one baffles me. I feel like you could write that website and app with 5-10 skilled employees and a handful more for support and administrative overhead, skim your 10% of a good chunk of all Internet microtransactions, and retire early. Then they go and nuke all their goodwill trying to milk every cent they can out of the process[1]. What the fuck? Just make a product people want to use and charge a fair price for it; payment processing with a small blog platform is not rocket science. No part of this requires 60 million dollars and 100+ employees[2].
