1. He put his own five minutes of fame as more important than the enjoyment and effort of millions of other people around the world (the boat race is a global event screened in 50 countries and with large viewing figures in the UK). People who put themselves above others are always, always worthy of contempt in my eyes, whether they're a banker pocketing a bonus while laying off some staff or a dick in some speedos in the Thames.
2. His efforts meant the race had to be restarted, which in no small part culminated in the collapse, treatment and hospitalisation of a member of the Oxford crew. So not only was he incredibly selfish but his actions directly harmed others.
3. He knew he wasn't supposed to be there, there are enormous signs up everywhere telling people they shouldn't be there, he was in a sealed off area without the permission of the organisers. This alone is punishable.
4. Anything not covered above is covered in Malcolms excellent post.
It seems to me this is purely a question of "who" it affected, because they're all toffs and such (factually incorrect but there you go, I should have expected better than critical thinking on here when it comes to the Boat Race as was evidenced last year) rather than what he did. Pure Mailite thinking, playing the man and not the ball.
