I think the barrier to better OS is partially a bad device market. Smartphones are short lived products with specialized hardware and manufacturers do not share generic or reference drivers. There are some other factors, but I don't see how a development would be possible without close cooperation with the manufacturers. I doubt we would see the development of the personal computer again. The wrong people in business decide the direction here. I do even think this is ultimately a limiting factor. There is just so much I would ever be willing to share on a device where Apple or Google is the administrator. I mostly degraded my phone to basic communication and nothing else. No auth, special software or utility. If I invest here I very likely will be sorry later. Device manufacturers decided to go with locked down environment. I cannot really understand people that buy a Samsung phone. The amount of crapware is staggering. iOS is cleaner, but I also do not want to invest knowledge here either. Not even in the hardware if it could run other OS, even if it is decent.
