That's what I mean by a positive example

A fan project still encroaches and Blizzard as many have pointed out is well within their rights to do this

In case I wasn't clear enough, I'm not a fan of this move, I don't think it's a good thing they're doing, however I can't deny they can choose to do it

If we want their behaviour to be constrained, then we've got to either convince them otherwise, regulate away their ability to do this or weaken copyright to prevent this

That's the reality of the situation
