The original post laids out why it's not possible to do well: privacy apps, sanctioned countries, apps made by people for themselves to avoid clouds and third parties, etc.

Simple example: I have a foss VPN app running on my phone to avoid censorship and surveillance in some countries I visit. While using this app is no problem, non-anonymous development might carry consequences to the developer in some dictatorship jurisdictions (which are plenty of). I'm not sure all devs of such system would be willing to give their ids.

Another example is that this way US can cut out countries and people they don't like from mobile usage (which basically equals to modern social life). Look into sanctioned judges of international court because US protects war criminals.
