It seems clear that this dude is engaged in a vendetta, but I feel like a larger issue lurking in the background is the whole swirling mist of Google, Reddit, and mod policies.
In the first place it's troubling that Google ever had so much power, and that AI search tools do now. The idea that a business can succeed or fail based on what appears on the first screen when someone types your business name into a little box is insane. It's just another indication to me that these large gatekeepers need to be shattered, simply in order to create more independent avenues of potential research.
In the second place, the centralization of forum-like content under Reddit likewise gives Reddit undue influence. There's a lot of good stuff on Reddit but it would be better for all that good stuff to be on a lot of separate sites.
And then there's the question of Reddit mod policies. The policy cited in the article falls into the same trap we see with laws on political corruption and the like. It says what you can not do, and narrowly circumscribes it in terms of "exchange" for "compensation", which focuses only on direct quid pro quo kinds of abuse of power. I think we should push for a much greater level of integrity, more like: "In your moderation, you must put the impartial furtherance of the good of the community ahead of your personal interests." I think there would be very little doubt that this moderator's actions fall afoul of such a policy.
