A fairly realistic complaint about the poll is that there probably is a fair amount of selection bias in who chooses to respond. Most people aren't going to bother with a survey like that (I didn't). Note that if I *had* it would have been one more vote on the complaint side, since I am rather unhappy with the current state of afairs.
In any case, it is probably wise to take the poll with a grain of salt. Do keep in mind however that it does provide at least a small amount of evidence in favor of the proposition that many people are unhappy about the way some of the rules are being handled.
