<i>Why else would you give such liberal terms...?</i>
As Red Hat pointed out when they first announced this, GPL gives them a nice negotiating stick
for this sort of thing. RH sits down at the negotiating table and says 'either go away, give
us these very liberal terms, or fight us to the death, since less liberal terms mean we have
to shut down our business.' If the troll does not want to fight to the death and does not want
to go away, they have to settle for these terms. Unusual, admittedly, but the only option RH
has and hence the only option an anti-RH troll has.
