I tried doing that on my wikipedia contribution after being bullied by a sysop, my plea was ignored (actually removed from public view) and received a permanent ban from all wikimedia project instead, probably to ensure I could not keep asking for this. I was told creating such a precedent could collapse the whole wikipedia and that it was too big a money maker for them to let this happen. I lacked the financial means to enforce my rights in court so I dropped it and moved away from spending 10-14h a day contributing to wikipedia. The kernel is probably not as corrupted as wikipedia management is, so they may allow for rescinding GPL if asked but would that prevent the removed code from being added again rewritten or not? Could the original author sue for copyright violation ?
