Well, if you're overly formalistic, then Link is the guy who actually had his name signed on the paper for the company that did arrange the kickstarter. Never mind that he had nothing to do with the practicalities...
...or, if you're pragmatic, then it is easier to go after a guy who actually shows himself from time to time, than to go after Craig who has gone completely to ground. Never mind it is easier if you're american to not have to go after someone in the UK.
None of this, of course, has anything to do with who actually deserves to be chased down. But if you put morals aside and put convenience first, well...
