I think you’re overstating your own interpretation of what the author wrote. If we’re going to take your use of the word “exactly” (with emphasis) for real then I’d argue that the author offers no charitable reasons for why the experiment took place.
The closest that I think he even gets to one is:
> At first glance, it is funny and it looks like journalists doing their job criticising the AI industry.
Which arguably assumes that journalists ought to be critical of AI in the same way as him...
> that the author offers no charitable reasons for why the experiment took place.
Right, and neither did the GP. They both offered the exact same two reasons, the GP just apparently doesn't find them as repugnant as the author
