We release full schematics for all of our products. Raspberry Pi does not.
We have already provided porting guides and tools on our GitHub.
Proprietary standards are not “libre”. Again, you fundamentally misunderstand what it means. Raspberry Pi does not release firmware or schematics. Numerous times they have locked out vendors trying to build compatible accessories in closed source firmware.
We are sticking to our position. We are pretty much the anti-thesis of what Raspberry Pi does in terms of creating an ecosystem. We only invest in upstream open source, nothing else. There are plenty of cheaper proprietary platforms but good luck getting them to work.
