“ Microsoft and Playstation also allow for cross-platform play, and crucially unlike Apple, actually provide a significant amount of services to developers for their cuts, including but not limited to QA services, SDK and hardware support from actual MS/Sony employees, and marketing spend”

I don’t understand how this is materially different from apples investments into Xcode, discoverability & promotion in the App Store/“marketing spend”, etc. Apple does tons of stuff with the big players behind closed doors, they highlight it every keynote and that’s just the ones they talk about on the “real human being” front.
