Well, if they went to court they might win, the defendants might win on the grounds of fair use, the problem is it's hard to tell in advance and it costs you a lot of money to go to court and find out, so those people probably didn't have enough money to stand up for what are possibly their rights, plausibly their rights. But because of the way fair use is defined in copyright law it's not a clear permission. It's a rather vaguely-drawn defense against charges of copyright infringement.
