legal: change license to GPLv3 in script headers Kept wondering wether I should keep the MIT (because I highly value freedom of act) or embrace the GPL (because I don't want this work to become close-source). I do understand that this commit (and the next one that is actually changing the LICENSE) is a defeat for freedom. I guess freedom has been defeated long time ago, when people and companies figured that was "free" (as in gratis) was also "free" (as in disposable). This is not how I think free (as in "libre") works but hey, that surely is how Intel and other corporations see it (ec: Intel Management Engine is entirely based on Minix, is close-source, and *maybe* used as a backdoor by anybody). It boils down to the Paradox of Tolerance, and I surely won't tolerate shit going their way. If you want to take open source stuff, be my guest ; but you have to play by the rules.
