In the end they will make Apple disappear from the European market.
The European Union lately the only thing it does is to prohibit, demand, demand, demand and continue prohibiting. Everything is excessively bureaucratized, everything imposed, laws and more laws, some with more sense than others.
The truth is that having Android in Europe a significantly higher share than Apple, having such operating system that allows everything you want, I do not understand that those who use iOS in Europe, is around 25/30%, and we know the existing limitations, but still use it because we value other things, do not want to allow us. For tinkering there are already a thousand Android phones and thousands of Windows computers, Apple offers a closed system, with other advantages and disadvantages compared to its competition, but manufactures 4/5 products of each line. There is enough variety and supply for those who want to use other app stores, do it.
However, it is true that in this issue there are Apple policies that I do not understand, for example, the issue of xCloud, Steam or other gaming platforms to which they put a thousand obstacles, it seems that all they want is to enhance their Apple Arcade, when this service is quite disappointing and I do not think it is one of the best performing among its various subscription services. In this sense I think Apple is holding back the competition and perhaps this should be seen, not as an opening of the operating system to different platforms, but to be able to use different monetization services or to be able to play "cloud" game services.
It is not an easy issue, but the raison d'être of iOS is its "closed" system. If you like it fine, if you don't like it, you have Android with lots and lots of variety of brands and handsets and customization layers, ROMs, etc.
With what the EU is proposing, the only thing they seem to want is to open security holes in a more closed and secure system for the average user.
