I’m writing an app that I will distribute only through f-droid. The people I would like to share it with are typical, non-technical android users. Before those changes I could just send them a link to f-droid apk and explain it’s just another app store or send a link to the apk directly and probably most of them would be able to install it. Now I would have to tell them to do all those weird things first, things that look suspicious and that they would not understand the purpose of. I don’t think anyone will be wiling to do it. This is not a win. The effect will be exactly the same - serious limits on distributing apps though alternative channels.
