I read through some of the discussion on Wikipedia. The operator of the bot comes across as agreeable and arrogant at the same time.

Questioned about it, he's asking his rig why it did something and quotes verbatim from the generated text. Then when a Wikipedian asks how the bot logged in, berates them how it's all ephemeral code and he could only guess.

If you want a glimpse into the mindset, read this interview: https://www.niemanlab.org/2026/03/i-was-surprised-how-upset-...

The overall attitude is that this was going to happen anyway and we should feel lucky he's so helpful. I rather agree with another commenter here that this was "pissing in the fountain". Whatever pure motivations there may have been, cleanup was left to others.
