To grow the ecosystem, AMD needs more people working on their hardware. Restricting Linux will only alienates students, hobbyists, and devs who want to adopt AMD tech.

- From long term AMD user

I want a robust open-source ecosystem where anyone can take my hardware projects and modify them without needing to deal with licensing friction.

The market is full of dark patterns, and vendors like AMD/Xilinx can pull shitty moves like what OP highlighted, knowing there is no decent alternative (Altera is another disaster). Lattice had the opportunity to fully embrace opensource toolchain and try to disrupt from the bottom, but they seem stuck in the middle, not wanting to commit one way or another.

I'm grateful to SymbiFlow, and IceStorm and others, even though they obviously lack support for proprietary hardware features.
