Just in case I was still unclear:

The point about nudes was an analogy for companies to not leave themselves at risk by doing the WLAN version of walking around with nothing on.

The other point was more obvious. making use of bandwidth that you don't own/lease/have-rights-to (and other network pranks) is a "no-no" even if there is no way to catch you.
But merely connecting, getting an IP and (descreatly) looking around is not something I would consider any different than turning on a TV and getting to watch a private M$ meeting that no one in the meeting knew was being broadcast. (aint no crime)
