Who is forcing you to install apps from any store?
Are you being held hostage and compelled to install apps against your will? Blink twice for yes, three times for no.
Ohmygod I can't deal this reductionist stance on choice. Software isn't fungible. If you, for example, want to play a specific game, need a specific messenger to talk to your friends, or need a specific app for work like the Adobe suite or Procreate then you have no choice but to go to a store where those apps are available. If Photoshop is only in the Adobe store then you're gonna have to download and use that store if you want it. Having the choice to not use Photoshop isn't the same thing as having the choice about where to buy Photoshop.
