I'm with you here. I think Apple should let you install whatever OS you want in the device after the support cycle ended. But that's not gonna happen any time soon. Until then, we jailbreak.
No OS exists because everyone knows it couldn't be installed in the current status quo. Why would anyone do the work of porting $OS to old iPads if they knew it was fruitless? How could they even do it?
Apple needs to step TF out of the way. They sold this hardware, they got their money. Move aside and let people use what they bought.
There aren't because non-x86 computers are really poorly standardized. Most x86 PCs probably are capable of natively booting MS-DOS for an IBM 5170 PC/AT but iPhone 17,1 and iPhone 17,2 run completely different images. Efforts like PostmarketOS have no chances of success when literally everything is model subtype specific.
