I hope most people realize these rules are to protect consumers by giving them the freedom of choice. If big tech companies try to lock you in or misuse their power, it’s great to have those rules as a consumer.
If you don’t agree with it, you can just use the AppStore and all the default apps Apple is giving you. Nothing changes for you!
But now you’ve the possibility to use other stores, apps that weren’t possible before.
Be glad the EU uses their power by giving you freedom.
Otherwise we would still have the lightning cable and the new iMessage couldn’t communicate other than with other iPhones.
These rules aren’t only for Apple but apply to all big tech companies.
