Well, with the important notice I do not know what's happened, having read only one part, my take is simple: why people develop for walled gardens?<p>If Play Store, App Store etc became EMPTY because the only apps are from big tech they totally loose any customers appeal and fails quickly. Remember the old concept of the union who makes the strength?<p>Personally I do AVOID as best as I can any third party walled garden and even developing on their APIs because I know their are closed hostile ecosystems. We have to accept what freedom demand and simply go a step at a time toward a ban by laws of any closed software, any walled garden and so on. A step at a time means start not working on, so for, them today, explaining why as much as possible and inviting people toward open platforms. If you really want Android there is F-Droid as a middle-ground.
