I think you're reading a lot of intentionality into the situation what may be present, but I have not seen information confirming or really even suggesting that it is. Did someone challenge them, "was AI used in the creation of this article?" and they denied it? I see no evidence of that.
Seems like ordinary, everyday corner cutting to me. I don't think that rises to the level of malice. Maybe if we go through their past articles and establish it as a pattern of behavior.
That's not a defence to be clear. Journalists should be held to a higher standard than that. I wouldn't be surprised if someone with "senior" in their title was fired for something like this. But I think this malice framing is unhelpful to understanding what happened.
