One thing the author doesn't seem to mention is how that video could actually raise revenue. I, as well as many others, had no interest in Australian Tennis, but upon seeing this video have suddenly become both aware and at least a bit interested in it.

How many people would be more likely to watch if they expect something similarly funny to happen?

I can't think of a single reason why someone who had the intention of watching the match would no longer be interested in it because of a two minute clip (loosely related to the match and not containing any "spoilers"). On the other hand I can think of a reason why someone who didn't know about or was debating watching, will now watch.

The clip added value, not simply didn't reduce it.
