“This makes grsecurity for Linux 4.9 the last version Open Source Security Inc. will release to non-subscribers.”
So, they gonna change their name to Paid Source Security Inc or something since they’re moving away from open-source? Seems to me like they got tired of the freeloader effect to open-source software, esp by commercial sector, to point they switched to proprietary software. I’ve been encouraging more experimentation on proprietary side with paid, shared-source software for that reason. Good news is the pirates will probably get lower security which might result in embarrassments for them later on. :)
Do they not still have to release the patches under the GPL to their customers? Could their customers not then distribute those patches as they see fit?
Yes, but then these customers would have access to the next patches cut off swiftly. And it is GPL-compliant.
That seems in rather stark opposition to the spirit of the license, if not immediately obviously the letter.
I believe it’s not, as the authors of GPL seem to argue: https://www.gnu.org/licenses/gpl-faq.html#GPLRequireSourcePostedPublic, and the question 2 places below (https://www.gnu.org/licenses/gpl-faq.html#CanIDemandACopy)
This post made me unclear on how open-source or proprietary it is:
