Did you ever consider that something isn't necessarily garbage, just because you don't like it? Personally, e.g. I don't like electronic music at all, but that doesn't mean it's all garbage for idiots stupid enough not to notice - it's just not my cup of tea.
More to the point: One can like "The Office" (as I do) and still dislike the ad. Just because you happen to hate both, doesn't mean they're one and the same. And it's not because the ad has Seinfeld (I happen to like him, too) or Bill Gates in it - it's because it's a poorly written attempt at comedy.
"The Office" has punchlines and structure, even though they're not as easily recognizable as in "classical" sitcoms and may not suit everyone's tastes. "Seinfeld" may have been billed as a sitcom about nothing, but it actually had very clever stories and gags.
This ad, as far as I can tell, has absolutely no punchline or point to it at all. It seems to be a feeble attempt to make Bill Gates look better, but doesn't add up to anything. And had it been Steve Jobs in there, it still would not make any more sense.
