I wholeheartedly agree about it not being unique to CNN. However, I don't think there's anything odd or misplaced about focusing on CNN, since the entire context is very specifically that of CNN+. I've seen many a similar comment here on HN about the toxicity of Fox News (which is just as bad) that made no mention of other new services like CNN and MSNBC. Your political leaning might influence which batch of toxicity you describe more, but they're all a part of the same putrid stew.
