The so many articles you read about Steve Jobs and the iPhone.
Did you once say/ask “it was not just Steve Jobs. It was a whole team of people who created the iPhone”?
The media and the public in general give him the credit because he led the team that developed the iPhone.
The first man to walk on the moon. He couldn’t have done it without a whole team of people working before, during and after they landed. Most of the media does not go into detail when they write stories about it.
It’s silly to say that everyone on a team should be mentioned by name in every article that comes out about an accomplishment.
And, yes, I personally do speak out when CEOs and such take credit. [The Google Android project head is one example from recent memory].
