Allwinner used to distribute "SDKs" which was their Linux kernel with binary modules for components that they could not open-source. Allwinner is a fabless semiconductor company and they source components from different vendors.
They did not know that they had to split the Linux kernel source tarball from those binary modules!
That wiki page is not constructive.
Doesn't matter whether they are fabless, or what they knew and when. They distribute GPL'ed software, they're on the hook, and they need to abide by the rules.
And after all this time and all the warnings they've received, it's not possible they're not aware of their obligations; they just choose to ignore it until the day someone actually sues them.
