To a certain degree sure, I’m still miffed at what they did for the steamdeck. Having custom drivers and configurations they never open sourced and have not declared any intention to open source. See https://gitlab.com/open-sd/acp5x-ucm-files#notice .

Valve is still a good advocate for open source, the support they’ve given to dxvk alone is worth praise. But they ain’t no angels.
