This is Alyssa Resenzweig. She reverse-engineered Apple's M1 GPU with no public documentation and also developed an open-source Linux driver. (programming.dev)

Part of why it happened for Apple's chips is that there weren't any Linux-compatible GPU drivers. It's easier to justify investing lots of time and effort into something like this if it makes hardware start working than if all it does is mean you're not using a proprietary driver and in the medium term likely have worse performance.

The other thing is that Apple chips use a modified PowerVR architecture, and not some proprietary architecture.
