And so is Arm, especially their Mali drivers.

While some go “um, ackchually, you don’t need a GPU driver for your hobby project of using a cheap SBC to run emulators”, it does affect usability a lot. Yeah, Arm also pointing at the licensors and so are licensors to Arm in this case, but it’s still not good that the only SBCs with relatively good GPU drivers for Linux are made by Raspberry Pi, and in all other case, you either need to pirate the drivers (!), use the tool that allows regular Linux to use Android GPU drivers, or just use the framebuffer-only driver with heavy limitations.
