Thank you for these links they are fantastic! I was aware of the procedural lock in via play integrity services and also the lockdown on side loading so that didn't get past me, but I wasn't aware google also wants to alienate developers now by requiring ID. It seems to me google want to now fully commercialize the platform, transforming it into the ad infested network that web2+3.0 already became. I think their plan, by alienating non commercial devs, is that all apps will run on their ad models and non without them will be left.
