Shows Brendan's maturity.
I am not sure what should be the appropriate reaction or corrective measure in these situations. We should talk more about handling these unfair situations.
Someone else can become more successful building on top of one's open source project. On a resume, a top contributor and a minor contributor to open source project might have same weightage depending on how you present it - making the situation unfair for a person dedicatedly working on a single project (quality) vs minor contributor to multiple projects (quantity).
But deleting name and credits is wrong. An acknowledgement from the benefitting person (if not the recognition/reward) has far more positive impact on career than justifying to other's that your work was stolen.
It was a bit strange to read some of the initial negative comments. I see Brendan being a sport. I would argue that reading the story as a report against unknown persons at Sun makes more sense. I don't see much sense in blaming victim. And, in my opinion, the VIP had a good run but he isn't the bad guy here.
