On the subject of GRSecurity patch to the Linux Kernel

[concernedfossdev]

To whom it may concern;

GRsecurity is preventing others from employing their rights under version 2 the GPL to redistribute (by threatening them with a non-renewal of a contract to recive this patch to the linux kernel.)
(GRsecurity is a derivative work of the linux kernel (it is a patch))

People who have dealt with them have attested to this fact:
https://www.reddit.com/r/KotakuInAction/comments/4grdtb/censorship_linux_developer_steals_page_from_randi/
"You will also lose the access to the patches in the form of grsec not renewing the contract.  
Also they've asked us (a Russian hosting company) for $17000+ a year for access their stable patches. $17k is quite a lot for us. A question about negotiating a lower price was completely ignored. Twice." -- fbt2lurker

And it is suggested to be the case here aswell:

"Do you work for some company that pays for Grsecurity? If so then would you kindly excersise the rights given to you by GPL and send me a tarball of all the latest patches and releases?" -- lolidaisuki
"sadly (for this case) no, i work in a human rights organization where we get the patches by a friendly and richer 3rd party of the same field. we made the compromise to that 3rd party to not distribute the patches outside and as we deal with some critical situations i cannot afford to compromise that even for the sake of gpl :/
the "dumber" version for unstable patches will make a big problem for several projects, i would keep an eye on them. this situation cannot be hold for a long time" -- disturbio



Is this not tortious interference, on grsecurity's (Brad Spengler) part, with the quazi-contractual relationship the sublicensee has with the original licensor?


(Also Note: the stable branch now contains features that will never make it to the "testing" branch, and are not allowed to 
be redistributed, per the scheme mentioned above (which has been successful: not one version of the stable branch 
has been released by anyone, even those asked to do so, since the scheme has been put in place (they say they cannot
as they cannot lose access to the patch as that may cost the lives and freedom of activists in latin america)))

@xoreipeip @grsecurity they call it a "demo" version "20:14 < spender> what's in the public version is < 1/5th the size of the full version"
oreipeip @grsecurity "20:21 < spender> also it wouldn't be as fast as the commercial version [...] there are missing optimization passes"
