A few ways:
- Apple engineers working on EU-mandated features aren’t working on fixing bugs/new features that are actually useful.
- Added complexity to the OS increases likelihood of bugs
- Apple decides a cool new feature that won’t fly in Europe due to the DMA isn’t worth further fragmenting the OS
- Wait until an app you use for your job decides it’s leaving the App Store. (Download Photoshop on the Adobe App Store! Don’t read the fine print, we promise it’s just as easy to cancel your subscription as it is on the old App Store. Adobe thanks the DMA for protecting EU consumers!)
If any of that is that onerous for Apple, they could have dumped that market of about 400M people. Apple chose to keep making the money, so obviously compliance cost is not overriding their profit motive.
And I'm in the USA... so the
ONLY place I can get apps "I need for my job" is the one App Store. However, if I was in the EU, I'd simply get a crucial app from the developer or switch to one of a dozen clones of any given app if I refused to get apps from stores other than Apples.
Since you brought up Photoshop as an example: several years ago when Adobe went subscription model, I opted to go Pixelmator and subsequently dropped all use of Photoshop.
Furthermore, this idea of companies yanking their apps from the App Store will likely result in them taking huge hits to revenue. There's more than a decade of all iDevice users being programmed to get apps from the one store. Yank your app from that store and those who don't even think about third party stores will no longer find & buy your app. I do believe some players will pull their apps... then miss the revenue from the "main" App Store... and put it back again. As it is on the Mac, there are third party stores and placement in the Mac App Store. Why both? Because they make more money by having their app where buyers are vs. demanding buyers buy from only a third party store.
Will there be exceptions? Yes... but clones- like that Pixelmator example- will step in seeking market share.
Again, if you- like me- are
NOT in the EU, we are merely witnesses to a market test,
unaffected by what happens over "there." The world is throughly programmed to get their apps from the
one App Store. That won't unravel overnight... and won't unravel at all if the best store is still
that store. Competitor stores will have to overcome the well-entrenched standard... mostly likely through better pricing, better value, bundle offers, etc... and still there will be the great hurdle of driving change from a well-established norm.
If third parties are successful, the one store will need to get more competitive to try to hang on to share... which will likely press Apple to revisit hard number commissions and other policies that led to GOVs having to get involved in this matter. Else, Apple can hold firm to "as is" and watch "better pricing" (and similar) elsewhere siphon away customers.
Competition is ALWAYS good for consumers. No competition is only good for the lone seller.
