Sure, but in war there is at least an exit plan (a way for eventually not having to kill anymore), even if it's shitty and ill-planned. If you are in software freedom for the purposes of abolition and you pick the GPL, you are allying yourself with people who NEVER want to give up copyright, because it lets them "exert control" over the end user, e.g. corporations, so your ally has a very strong real vested interest against what you take as a desired end goal.

What does the endgame look like for an abolitionist?
