I won't begrudge the guy for writing about his personal experience, especially since he was perceptive and honest enough to acknowledge his own mediocrity. Nor would I begrudge the guy for finding other white millennial men who have walked similar paths and felt similar feelings.
What I take issue with is his going back and forth between anecdotes and statistics. I take issue with him teasing a hypothesis that he's too chickenshit to full-throatedly stand behind, in the same way Elon Musk is too chickenshit to ride one of his own rockets. He'd rather just publish the essay and hand the baton over to the usual gang of white grievance blowhards.
What use is this essay? It's already being used as justification for anti-wokism. But if that wasn't his intention, what else could it have been? To be more charitable to him, he may have been trying to better understand why white men moved toward the manosphere and connected the dots starting with his own insecurities and resentments and arriving at some of the entry-level concepts upon which white resentment rests.
But if you really think about it, is "I was a liberal guy, until this one bad thing happened to me" even a unique story? The only difference here is that it's career shit instead of something mundane like a divorce.
