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 pressure from employer.

Some companies can go really hard on these metrics. Rare in the US but not rest of the world.

Or they had a bet in a prediction market.
