What level of profit would no longer count as greedy? What fee structure would also not count as greedy?
First, what is Apple's gross profit margin on the App Store? Second, what is Apple's net profit margin on the App Store? What profit margin (gross and net) is appropriate? Why is that level appropriate? If Apple has a lower App Store profit margin, is it acceptable to raise margins elsewhere to make up for it? If not, why? What company-wide profit margin (gross and net) is appropriate (i.e., no longer "greedy")?
Should Apple take a different approach to the App Store? Should they offer it as a free public service and receive no compensation? Should they increase develop fees instead of having a 15-30% commission (or no commission for free apps)? Does Apple charging a commission mean Apple is greedy but companies developing apps that want to use Apple's services without paying mean they are not greedy?
Complaints don’t help if you don't also at least provide a possible solution. What is one of your proposed solutions? It doesn't have to be ideal or perfect but I'm interested in what you think is a non-greedy and fair solution for all parties.
PS - and if you want proposed solutions, it's quite simply to allow sideloading and competing app stores.
Then you will find out what developers would actually be willing to pay to sell through the Apple name. Keep in mind that this is already what happens in macOS, and many (or most?) companies choose to pay 0% commission, and simply sell their apps via their own websites, and sideload.
And before you throw around the security excuse, again, macOS has sideloading, and there are no security issues. Do you think people are too scared to download a DaVinci Resolve installer direct from BlackMagic? Do you really think there is a security issue there? No, exactly. And thus why BlackMagic have zero desire to give Apple 30% of its revenues from thousands of hours of dev for the "privilege" of selling through the Apple store.
And yeah, I know, the next argument is, but Apple put all this work into creating macOS, how do they get their rewards for that. If companies like BlackMagic didn't write their software for macOS, then Macs would be completely useless. It's a two way street. Apple needs the developers, and the developers need the platforms. Apple provides macOS, and sells the hardware. The developers sell the software. Apple are just being greedy wanting 30% of gross dev sales too. Not even 30% of profits, but 30% of gross sales. Its just insanely greedy, and thus attracted all this heat.
And yep, I know all the other platforms charge the same commissions. Once Apple falls, the others will all fall too. But first you have to take down the big fish.
And btw, this proposal I've outlined isn't something new, it's been out there since day one. Regardless, the courts around the world are deciding, and it doesn't matter what two randoms on the internet say to each other.
