Seems fine to me
"According to Perens, "GPL version 2 section 6 explicitly prohibits the addition of terms such as this redistribution prohibition.""
But the GPL only mentions " You may not impose any further restrictions on the recipients' exercise of the rights granted herein." This means Grsecurity cannot prevent anyone from redistributing code. So if someone exercises their right to do so against Grsecurity's wishes, Grsecurity cannot really do anything about it. If the agreement is only limited to preventing release of future versions, isn't refusing future service within Grsecurity's rights since any business can refuse future service to anyone for any reason?
