Earlier quoted context omitted.
Not always, and not quickly. See http://nissan.com/ for an example that's been dragging on for around 10 years or so. He's not squatting on nissan.com per se, but in my opinion is fairly close to it. It's a David vs. Goliath situation that's for sure, I'm amazed he's managed to keep the domain.
Why do you think he is "close" to squatting? He registered a 'nissan' company in 1991, and registered the domain in 1994. Just because a 'big' company missed out - its not his fault.
I'm not saying he's a bad guy. Instead, I believe that the domain would serve a better purpose if it pointed to something that met the expectations of people who blindly type nissan.com into their web browser looking for an auto. Which in my case is exactly how I found out about it.
