What Amazon did with AWS they chose to do and has nothing to do with what Apple does.
AWS was obviously creaming users too much if they could afford to restructure pricing that much.
I've had a little to do with AWS for an app that was move to cloud. it had pluses and minuses. some issues were caused by the old code that didnt scale well to modern devices. they also couldnt give us a way to boot users off hogging licences.
the CTF I dont believe the EU set. Apple simply ditched the 3% they built in as payment processing and called the rest CTF. Now you could argue Apple is big enough not to be charged 3% but it's not hugely off the mark.
Even Epic have settled on a 12% fee after a year. What banks got in trouble here for using a honeymoon deal.
They are obviously trying hard to drum up business to any store they might release.
I find it hard to believe the EU is more consumer focused given the fine went into EU coffers not back to consumers
