I reccomend donating to postmarketos then. They do awsome work reverse engeeniering phones. Oneplus 6 is usable with pmos. Of course it has multiple problems but its nice seeing people make so much things for on old phones.
There are of course graphenos, calyxos, e/os/ of course. Unfortunatly the issue with every alternative os is that you need specific model of phone to even open bootloader.
