I don't agree with him as I mentioned the last time this came up if I recall. However before jumping on the situation, understand that he DOES have some legitimate points. As does the guy who claims he filed a patent on the concept of MMOGs back in like the 1980s along with pictures about how it would look. It might be the same guy, but I don't think it was.
Like it or not one of the points of copyright law is to be able to stake out a title, or concept, and not have to defend it from imitators or people stealing your name. I believe the issue isn't so much that Tim copyrighted the word "Edge" in all contexts, but rather within the context of video games and comic books, and what's more the copyright applies to titles more than general usage of the word. Looking at his site it seems that he is claiming he developed a lot of C-64 software in like the 1980s, while before the time of most gamers that does give him a degree of legitimacy especially if he's claiming his company has kept it's trademarks active despite not having capitol.
Don't get me wrong, I think he's responsible for what amounts to cyber-squatting (when someone gets a domain name in a celebrity's name for example and then tries to sell it to them), BUT one of the things is that the law is supposed to remain neutral on motivations.
I hope he loses, because he's being a jerk, BUT he does deserve his day in court (again).
The situation with MMOGs was a connected issue and scarier in a way (not sure what happened to that) since inventors and such can trademark/copyright concepts that they lack the capitol to develop. Patenting ideas and then trying to convince people to hire you/invest in you to develop them being an old, old idea and perfectly legitimate. If the guy had been shopping around the idea for a decade or more and then say Sony decided "hey let's produce this thing called Everquest, based on these ideas, but we won't bother to get the patent holder involved" that can be a problem, even if they didn't know about him specifically.
Copyright laws are one of those things that are easily abused, BUT there have also been situations where the copyright/patent holder has been correct and was a victim of theft.
