I *do* understand (to a certain extent) companies not being happy about employees using bandwith (and their time) for non-job-related activity. I *don't* understand singling out 'offensive' material. (Offensive to whom? I, for example, find material on some 'religious' sites offensive. So what?)

Then again, I think that worker productivity has to be the only measure. If my programmers churn out good code fast enough, I don't care whether they find it necessary to occasionally play games, discuss soccer, participate on this or other BBS or NG, or admire Jenffer Lopez' tits (or Long Dong Silver's, er, long dong). I don't like them download movies or music, but that's because of laughable bandwith we have.
