Earlier quoted context omitted.
The choice that people want is the ability to have other App Stores, or direct installation. This changes nothing for people like you while giving more opportunities for others.
I think 30% is absurd, but that would definitely change things for every user. I don't want to install Adobe's store because I need to use their PDF reader. I don't want to install Microsoft's store because I need to use Teams or Outlook for work. Other App Stores mean that companies get to make that decision--not end users. How could it be otherwise?
Why would you limit everyone else rather than make a choice for yourself?
