First off, is it illegal? Is it immoral?
There is an entire section of Super User devoted to breaking the TOS of hardware that I believe are perfectly legitimate questions.
I don't believe that the hotel internet question on SuperUser on Super User should have been closed. It asked a common, legitimate question that does address a concern of many people. If someone was Googling this topic, wondering if it was possible or not, hopefully they would come across the Super User question and see that it might not be the best thing to do*.
*I know it is wishfull thinking that we are going to chage these peoples opinion's, but it still is a valid point
I guess in the end I am up for questions of this kind, as long as the answer is "don't do it." I know that is kind of censoring the answers, but I do beleive there should be questions on Super User addressing issues such as these, stating that stealing wi-fi or bypassing Windows' activation is wrong (if not illegal).
