Good. Apple needs to comply with European law if it sells products in Europe. Just like how European countries have to comply with US law to operate in the US. It's kind of bizar how many people in this thread seem to imply that US companies somehow don't have to respect local laws. Why wouldn't they? That's how business works in every country. Any company always has to comply with the local laws of the country in which they're operating. Why would it be any different for Apple?
People also seem to be forgetting that there's also an antitrust case against Apple in the US, for many of the same reasons as in the EU.
The idea of Apple pulling out of the EU is, simply, absurd. The costs of complying are minuscule compared to the profits they'd lose if they pulled out of the EU.
Also, anyone in this thread who's enjoying playing on an emulator on their iOS device should be thanking the EU for these laws, since the Digital Markets Act is the only reason Apple now allows emulators in the App Store.
