While their response is pretty roundabout, my experience with moderating/owning several community sites is that advertisements for competitors really are one of the largest categories of spam, and I wouldn't default to reading an attempt to mute them as a "shady tactic."
Think about the point of view of a founder-developer. You have a list of bugs to fix, a bunch of people to meet with, etc., all while manning a pool of servers to make sure they stay up. Someone says to you, "hey, we're getting a lot of spam from/about this company called Fade." I'd bet a lot of programmers would just write "if 'fade' in message" before getting back to work on other things.
