I think that's a stretch. There was a clarification earlier in the article about the difference between a one-off piece of criticism and a pattern of obsessively negative commenting on everything you do. A critic might respond to every Tesla mention on Elon Musk's twitter with a negative response because they think (rightly or wrongly) that the company is overhyped. A hater would do the above but also respond negatively to him posting a picture of a sandwich he made and say that it's a terrible sandwich just because he made it. I took the article to encourage trying to differentiate, and if you find yourself interacting with the latter, then not thinking much about them seems like a valid technique.
