Tim Sweeney has stated in the past that he feels like there's a better argument for game console makers taking a 30% fee.
>"There's a rationale for this on console where there's enormous investment in hardware, often sold below cost, and marketing campaigns in broad partnership with publishers. But on open platforms, 30 per cent is disproportionate to the cost of the services these stores perform, such as payment processing, download bandwidth, and customer service.
Basically, he feels that these platforms might actually be doing enough work to earn a 30%. It's not that crazy to criticise one company taking a big slice and approve another company taking a same slice if they are bringing different value.
You appeared to have carved out a convenient exception for the Playstations and Switches of the world because your intuition tells you that the industry isn't healthy, and that wobbling it a little could kill company interest. But we still have nothing to anchor the belief that 30% is right for gaming consoles but not elsewhere.
You don't have to agree to Epic's terms to access the platforms from Sony, MS and Google. You do, however, have to agree to Apple's terms to access their Platform.

And I'm sure they're not happy about the fees on other platforms, but they can't fight everyone at once.
There is no incentive to stay competitive by cutting down on your slice of the pie.
Epic, btw, has the exact same kind of agreement with Sony, Microsoft, and Google, for access to their gaming platforms. All three of those companies are extracting the same 30% fee that Apple is.
But now Epic has decided to grandstand and pretend that Apple has a "monopoly" and protest paying Apple, while still happily paying the exact same fees to its other gaming partners, including to Sony (for PlayStation), which just invested $250M in Epic.
So to say that there is "absolutely no basis" for Apple's action just isn't true.
