There is no “hard” limitation differentiating guzzling down a gallon of gasoline vs a gallon of red wine; nor is there any “soft” limitation of deploying your own OS.

Vast majority of people do not possess knowledge to extract consumable ethanol from gasoline, doesn’t mean it is impossible.

Vast majority of people do not possess knowledge to attempt to deploy their own OS onto an iPad, doesn’t mean it is impossible. Very talented individuals have been hacking iOS boot loader since original iPhone (no version, no suffix) days.

If one are so inclined, there’s plenty of places to learn, and expand one’s knowledge to attempt what most aren’t able to do. The alternative? Bitch whine complain and repeat until a multi-trillion company give a damn. I ain’t holding my breath.
