I think blanket rules like this are a bit silly. Clearly PP (Powerpoint) has its uses. A picture is still worth 1000 words.
My suggestion would be to have a default ban, but insist that if a presenter really "needs" to use PP (s)he should have to get some sort of permission first. The reason for that is that the person wanting to use PP would then have to consider and justify its use before using it. Basically, just give them pause to think and consider.
