You imply as much when you suggest that they must send C&Ds to the guy. They don't. It does not hurt their trademark use. And if your intent was to suggest how they weren't being extreme, you did not make that clear in anyway.

The belief that you have to enforce a trademark to the point where you have to threaten even innocent use of that trademark needs to be shot down. It's an annoying meme that needs to die. Hell, even a lawyer is saying what I'm saying.
