A monopolistic operating system which has a strangle hold on mobile computing. No matter for it's base being Free Software, most devices are downright required to be preloaded with proprietary software for them to function in the real world.
My dream is for one day to either create an ecosystem of software (possibly even over Android!) which contains no proprietary software and ensures as much user freedom as possible.
However for now, I consider it much better than Apple's iOS and the Pine Phone unfortunately is not good enough for daily usage to replace Android for me.
