Brad goes into this here. Grsecurity has written extensively about this.
Read the links to their site where they go even further into detail.
Grsecurity is not violating any license. There are multiple quotes from authorities on the matter in that link. If they were, so would Redhat, Canonical, etc.
If I had to deal with constantly having my name dragged over something I wasn't doing, I would probably be pretty upset about it as well. Further, the Linux Kernel community tends to have... some negative communication patterns.
But the content is very valid, you should give it a fair read, regardless of how you view Brad's language.
The comment they're replying to is also not exactly smelling of roses. It makes some pretty unsubstantiated claims.
I read Peren's claims, and IMHO they're very thin. It seems to be a classic case of "I don't like this" (which is fair enough) and then trying to find "objective" arguments to support that position. Not impressed.
