You are spot-on... thank you!
Very helpful what you wrote (also about rosetta not being uninstallable).
Maybe it's a sort of habit of me, to not have stuff installed which I do not (want to) use (at all)?
But yes, maybe I'll use the AppStore-Version for a while... I just have less trust to Apple when it comes to "security" products, that's why I prefer to get them directly from the developers.
