id Software's John Carmack updated his .plan again today with some harsh words for the people responsible for taking down the QuakeLives site in retaliation for the author's decision not to abide by the GPL license (story). Here's what he had to say:

Some people took it upon themselves to remotely wreck Slade's development system. That is no more defensible than breaking into Id and smashing something.

The idea isn't to punish anyone, it is to have them comply with the license and continue to contribute. QuakeLives has quite a few happy users, and it is in everyone's best interest to have development continue. It just has to be by the rules.
