Looks like Epic is getting almost everything they wanted from both Google
and Apple, given that EU is giving their hands to do all the jobs necessary for the Apple's case. Those two stores will remain dominant (>95% share) for a foreseeable future, but at least customers will have a choice.
Now I wonder what if Google/Apple decided to decrease their cut to a more reasonable level, around 10~15%? App store/Play store fees are not their primary revenue stream so this must be a reasonable cost for them to mitigate this kind of legal risks, but they choose not to do so.
