Support for all the hardware so we can quit using garbage Google-provided Android on every single phone instead of just the half-dozen or so phones some of these Free Android builds support. Amazing that I can install Linux on every single freaking configuration of PC that's ever existed with a very tiny amount of systems not having support for all of its hardware even if said hardware has never been freed or even officially documented, but not with phones.
The damn things will still be a privacy nightmare because your cell signal tracks you everywhere you go, but at least we'd have a Free OS for everyone's phone.
Contributing to github is contributing to Microsoft's AI poison which can steal your code from you regardless of license for another project that might use an incompatible license. To hell with github.
