Look at it this way. Matty registered ntlcommunity.com long after NTL had made public the fact they were going to have their own help site with that name. Cybersquatting is now against the law. NTL would have won had the case gone to court. If you ask me, the idea was to deliberately trap people who would be looking for the 'official' Community site, and I don't like that.
For example, if eBay announced they were going to set up a new car auction service at motoring.ebay.com, would it be okay for me to go and immediately register the domain
www.ebaymotoring.com? I think not.
