@lxo siding with whom? And who said anything about crediting only the kernel? At this point, I have no idea what you are saying. So, I'll stop.
Please remember, GNU insist on calling only the kernel as Linux and in turn demand to be credited as GNU/Linux, above all the other software components that goes into building systems these days. Rest of the world isn't as pedantic. GNU would be credited far more often if people didn't have to avoid being associated with the toxic brand it has become.
