You can’t gatekeep something that is freely available on another operating system. The problem is, people want to have their cake and eat it too.
They want the benefits of iOS AND Android. And while there may be nothing inherently wrong with that idea, it’s not a very practical request.
There are features that make Android better in some respects and there are features that make iOS better in some respects.
If you want security and optimization, choose iOS.
If you want freedom of choice above all else, choose Android.
I find it absolutely disgusting that the EU would use legislature to tamp down another company’s success simply because none of their tech companies can match it.
