PhiHo,
On the other hand if he got his job not because of his talents in marketing but just because he is an actor with skills in special effects then it is really non-sense
As far as I know, it is not a job. Making PSA usually means that it is done at no charge.
At the holiday season, people, even including talent agencies, feel to do some generous activity, such as helping OLPC.
The G1G1 program did change the landscape. Some stuff Nicholas said last year don't apply to the situation now.
