The article makes it sound like he was willing to sell very cheaply on the condition that the new owner actually use the domain and not resell it. That's not really squatting behavior.
"Mehta made it clear he was interested only in the name and Kneen reconsidered briefly, even proposing some restrictions including a required payment if Mehta resold the domain. Ultimately, however, Kneen refused to sell."
A startup tried to buy a domain and failed. So instead of moving on, they decided to sue. Sounds like a winning plan to me.
