The thing is, the league has no means of making a distinction between those who watch because they find the tournament exciting in and of itself, and those who don't like its gimmicky nature but watch anyway. And even if they did, they would most certainly choose to ignore it. If you watch, you're going to get chalked into "it's a success" column no matter what.
Sure, one might say there's little point in not watching since you're just one little piece among millions, but if enough of those millions chose not to watch either, there WOULD be a statement.
And, at the very least, if I don't watch, and they choose give this idiotic idea another go (or pull out of the olympics as a result), at least I have the moral high ground when expressing my displeasure about that. The little lambs who don't like it, but chose to watch anyway, do not.
