"This is conjecture on your part, and I can say with 100% certainty that it is untrue. I am the Sony engineer you referenced in your article, and this is not my intent."
and yet you said in that wiki page:
"As part of their request to remedy a busybox GPL violation, the SFC does ask for source code unrelated to busybox. Personally, I believe this is improper. However, the main reason for this project is to avoid having the SFC gain review authority over unrelated products produced by a company."
The 'Linux kernel' is part of the 'unrelated products', hence by your own admission the 'main reason for this project is avoid having the SFC gain review authority over' the Linux kernel.
