Someone must have really wanted to put this on their CV.

First thing that came to my mind... why people are so self-centric... and yet, somehow, you feel bad because the same people flex with these CVEs while you can't tell a single huge one you had found under NDAs, while they keep downplaying or ignoring you. I think its better to treat these people as less professional, and try to influence the common reception what is actually professional and what is not.

Or they had a bet in a prediction market.
