The Digital Markets Act is all about profit-motivated businesses. It regulates markets, not charities. It's not anti-profit at all, just pro-competition, and Apple was attempting to stifle competition.
The entire point of DMA is to make sure platforms can’t use lock in to prevent others from joining the market for digital goods and services.
What terrifies Apple isn’t Fortnite, it’s that Epic will make a *better* AppStore.
That being said: it's probably a good thing it was Epic that Apple went after; Apple would probably have gotten away with going after a smaller company.
What's to prevent them from changing their mind and blocking Epic again? What if Tim Sweeney says something else to hurt Apple's feelings in the future? Apple has too much free rein over removing access to this market, and while it may be a market that Apple has made, the EU is clearly requiring Apple to open up the market for others with the only restrictions being those where the app store or the apps themselves are damaging to consumers in the marketplace.
They almost certainly are, which is why the reasoning of EU’s predictable involvement was what triggered Apple’s reinstatement of Epic’s account seems dubious to me.
