same to my. actually only the summary of the history was from a different user. the content itself was mine.

The claim made at the time was that the titles were not from other people and were in fact caused by the model hallucinating after the input query timed out (or something like that). Obviously that sounds a little suspect now, but it might be true.

That's a lie if so, if you look at the Reddit threads there's no way those were not specific other users histories as they had the logical history of reading browser history. Eg, one I saw had stuff like "what is X", then the next would be "How to X" or something. Some were all in Japanese, others all in Chinese. If it was random you wouldn't see clear logical consistency across the list.
