Wasn't there some recent drama where the grsecurity folks were going to stop distributing it for free?
Yeah. Was following on from this, https://mobile.twitter.com/marcan42/status/72474588679483392....
The stable patchset, yes. In fact, they are using legally questionable tactics (acting in bad faith) to try to deny users from distributing their GPLv2 stable patchset. I personally don't trust people who have such questionable morals, regardless of what technology they happen to have created.
Security issues fixed and announced a month ago are only just now available for TAILS users. https://tails.boum.org/security/Numerous_security_holes_in_2...
TAILS still doesn't ship with a grsecurity-hardened kernel.
These might not be big deals if TAILS wasn't designed specifically for high risk users. Maybe they need more funding and open source love?
