I understand them having to protect their trademark. I actually went back to that link, and the article itself is no longer available, but it stated that they were in a suit against a lady in either Washington or Oregon that had a consignment clothing store that had the word monster in it, and also against a man that had a line of ski instruction videos for kids called either snow monsters or ski monsters. I don't see how this is infringement on the trademark Monster Cable holds since they are nowhere near the same industry.
I doubt that GM ever went after Regal (kitchen wares) because someone was going to make the mistake that they were cooking on a Buick frying pan. Just like no one would possibly think that if it weren't for Monster Cable, then we wouldn't have Mike Wazowski and Sully. No normal person would make these kind of connections. I never once thought while I was posting my resume--"Hey, these online resume guys make a killer guitar cable, too."
They may have the legal recourse in these matters, but it's pretty ludicrous at the core of it all.
But, hey, they may make a great product, I don't know. Sorry if I raised eyebrows--it wasn't my intent.
