I've long been a supporter of the first-come first-serve domain name policy. I would never want any of my domains taken from me, because someone thinks they have more of a right to it.
I agree with this in a general principle. For instance, someone has already used "Fabris.Com" because their company is named that, and they got there first. More power to 'em. If I'd gotten there first, I would have stood my ground and said, "I don't care if you've trademarked the name Fabris, it's still my name and it's still my domain."
But domain-name squatters are a whole different story. The people who squatted on Riocar.com don't have any reason for owning the domain name other than to extort money from Rio. This is, in principle, evil. In these clear-cut cases of cybersquatting, I'm glad that the rightful trademark owners can come in and claim it.
For anything in the gray area in-between these two extremes, we have the legal system. That's what our legal system is for. If there were no gray areas, we wouldn't need judges.
