First time on the Internet? Surely you don't think that all the people commenting online are experts in the topic being discussed. Whether he is an expert or not, just because you don't like him, you tell other people not to post his articles. Personally, the only thing I know about the guy is he coined the term "enshittification", which some people don't like, but he was right in his description of the term. Otherwise, we'd all be using Reddit still.

It's the Internet. People are going to do or say thing other people don't like. Don't take it personally.
