On the other hand, given that for a large set of content publishers Adwords provides a substantial revenue stream that will suddenly deplete. And given that this would probably be a larger hit to their pockets, the number of people who are actually in trouble would be larger in case Google cookies are blocked. I think # of support tickets, if that is a parameter we are judging the effect with, would be larger for this case.
ah, I was thinking more about pitchfork wielding users deciding whether or not to switch browsers (depending on how hard Microsoft pushed the blacklist additions, that could lose a few market share percentage points in a day or two), but based on the support ticket metric, that's a really good point.
