He did not apologize for his actions.

He apologized that silly emotional people got upset at the obvious outcome of this entire stunt.

A sincere apology takes three words. When those three words are buried in hundreds of words of qualifications and context its no longer an apology.

The entire thing is redolent of a condescending tone. Sam, you see, is a scientist! Anyone who questioned his behavior is just an having an emotional reaction and does not understand the real world - where there is always a Sam to piss in the well.

The thing is, most of use knew this already, and his demonstration did not teach anyone anything other than about Sam's character.

EDIT: Oh, I don't care about the gift card. I am simply commenting on the 'apology.'
