Hey there, I hope this email finds you well. I am writing to report a potential SOF license violation.
A person by the name CoolStar (aka starplayer132 and coolstarorg) is a developer in the custom Chromebook modding scene who creates drivers for Chromebooks running Windows 10/11. They sell SOF drivers for $10. However, when the driver is decompiled/deobfuscated using a reverse engineering program called Ghidra, the strings in the binary are identical to the ones in the Linux driver.
Here is a function from the Linux driver found in the Windows one:
The issue is that this SOF-based driver is closed source and, most importantly, paid, which completely violates the GPL license the original driver is using. Only about 15% of this code is their own property if you exclude the DRM inserted to paywall users from a simple audio driver.

Thank you for your time. Have a good day. You can contact me from this email, meghann6@proton.me.
