He said the crawlers were costing him money. Maybe stealing could be viewed as avoiding the ads? Don't know what license he had on his publicly available content, but if his site was not being crawled heavily, then it sounds like he might not have taken it all down. I wonder about hosting it on Github / GH-pages or something. Maybe at some volume it becomes a problem or maybe they disallow ads which he wants to profit from?

I used to follow him years ago and liked his content but I drifted away long before AI.

I wonder given his deep expertise how much he could get into teaching how to spot and fix bad AI JS code.
