I think this misses the forest for the trees here. The platforms behavior here is a symptom and not the core problem. I think the following are pretty clearly correct: 1. It's your damn phone and you should be able to install whatever the hell you want on it 2. Having an approved channel for verified app loading is a valuable security tool and greatly reduces the number of malicious apps installed on users devices Gi…
I don't understand what you're saying. Are you saying Google is making it harder to develop an app for sideloading than to develop an app for the Play Store? I don't see how that's the case. AFAICT, the new "sideloading" requirements aren't more restrictive than the Play Store requirements.
Disclosure: I work at Google, but not on Android.
