Zitron makes too many "mistakes" like this to be taken seriously. In other words, he just isn't the right person to make the "huge AI bubble" argument because he doesn't understand (or he's being dishonest about) the financials.
I wouldn't consider OpenAI's financials to be pretty. There's circularity in the market that is a bit concerning. And while OpenAI's unit economics have improved it's still questionable as to whether the R&D and capex expenditure ever aligns to the business.
But Zitron is too sure of his argument (without the credibility to support that confidence) and is trying to pretend that there's absolutely nothing of value here. My best guess: there's some "irrational exuberance" and malinvestment but there is something real here and the unwind of the irrational exuberance and malinvestment won't be nearly as painful as Zitron believes for a variety of reasons, including the fact that there just isn't enough leverage in play.
