Linus should be sued on a detrimental reliance theory. He said if anyone violated the license they'd be sued. He induced us to contribute our labour on that lie.
He won't sue. He won't even speak.
Same for RMS and GCC. Same lie. They even had us sign over our copyright "because we need standing to sue" (actually it was because they knew we could unilaterally rescind licenses from free-takers if we still held the copyright)
Grsecurity is violating the share-and-share alike terms in the GPL: which is the REASON we contributed. Which Linus and RMS constantly shilled 20 and 10 years ago: If anyone violates we will sue them.
They won't even speak on the issue. Not a public word.
