Around 10-15 years ago you could get a completely stock Android from China with basically zero branding, fully unlocked and easily rootable, removable battery, expandable storage, dual DIMs, etc. at a great price. I have a few. Unfortunately many of those small honest OEMs appear to have disappeared, and the bigger ones left have turned scummy.

Microsoft does similar and worse on Windows. This is capitalism being capitalism. Nothing chinese about it.
