I don't know what the fuss is about. It sounds like he expressed himself quite clearly and accurately. Not sure what his success has to do with him being able to criticize Twitter's decisions.
This article just reads like someone who is crazy obsessed with trying to put down Tim Sweeney. After reading the article, I left with a more positive outlook about Tim Sweeney and less of a positive outlook on the author Luke Plunkett and the website kotaku.com which seems to think this is newsworthy. If I had to guess, Luke Plunkett is one of those Elon lovers that is trying to swoop in to defend their glorious Musk. I recommend that Mr Plunkett try a little harder, because his conclusion of "This man complaining about high school cliques and supposed “elites” is 52 years old and is worth almost $5 billion." is not the mic drop that he thinks it is.
Now, I'm just a man complaining about a man, who is complaining about another man, who complains about the largest social media network's silly policies; but maybe Mr. Plunkett should recognize that Mr. Sweeney is allowed to have an opinion, and that Mr. Sweeney's success does not mean he can't have an opinion on that topic, nor does it mean that he is a hypocrite for having on. If there is any hypocrisy going on, it is likely Mr. Plunkett's stance of "expressing his opinion that someone else's opinion should not have been expressed". Maybe Mr. Plunkett should look up with Ad Hominem means.
