This strikes me as a rather uncharitable view. I think it's okay for people to be proud of their work on a difficult project, and want to have their names on it.
For many years now, NASA has let random people get their name printed on the Mars missions on a little plaque. Perseverance has 11 million names bolted onto the frame. My buddy boasts that he has been on Mars N times.
