Well, in this case, the question is will some people that have shorts and have to pay higher premiums decide to drop them if the offer sits for a while and continues to affect the market, if they expect it to go through? Does getting more exposure in the media affect the companies in a lasting way beyond the timeframe of the deal?

In a perfectly rational and efficient market the answer would be no. I don't think we're in a perfectly rational and efficient market. So I guess the question is whether the market is irrational enough or inefficient enough that there's some way to game the side-effects of this usefully.
