Optimising for profit happens to be more effective than what the EU does. Apple can convince bystanders to spend days working hard to trade for a phone. They do that entirely with good design, strong QAQC and persuasive advertising.
The EU gets convinces people to do things with fines and, ultimately, threats of jail time.
Now if one design people want to own and the other design only takes hold because of threats and fines, we ought conclude that the mandatory design is the weaker one. People aren't paying for replaceable batteries. They're paying for tough, cleanly built & waterproof phones. That is why there are sometimes actual queues outside Apple stored as people try to buy iPhones - people really think Apple designs great phones. For the EU to manage that they'd need a man with a truncheon standing off to the side forcing people to line up when they don't want to.
And they're doing this while Europe is being hit by crisis after crisis. This is a terrible time to be trying to reduce the quality of phones in the EU. It is bad enough in a good year. It is a terrible time to be drawing attention away from the actual problems that Europeans are facing. They should be working on making things cheaper and better for EU citizens.
