This is about which FOSS devs are making bank off of FOSS. There are TWO(2):
*Linus Trovalds *Bradly Spengler.
*Linus Trovalds is paid 1.3 million dollars per year likely under contract to forgoe the excercise a legal right he has: to sue violators of his copyright.
If he violated that agreement, (identified) third-party beneficiaries to that contract could attempt to seek to recovery of whatever liquidated damages are specified in that contract.
*Bradly Spengler simply adds a No-Redistribution clause to his linux-kernel patch. As he notes: the FSF and _SFConservancy_ all support him in this (it's 2020, he started doing it years ago, they have said nothing against him)
>>LOL. " #GRSecurity violates both the Linux kernel's copyright and the #GCC #copyright by forbidding redistribution of the patches (in their Access Agreement): which are non-seperable derivative works...
