They don't care what the courts say or think. They've had founders get in trouble before, the site kept going. The servers were seized, the site kept going.
And after this... well the site will still keep going. That will never stop. People will always keep running torrent sites, and there will likely always be people from The Pirate Bay who'd set up their own version/fork/whatever the second it goes down.
In other words, this court ruling will mean nothing for it. They didn't care before, and they probably won't care now either.
