>Given that SF employees have presented at many conferences in the past I don't see that getting official approval for the presentation is that strange.

It's not strange at all. So dig up some of those slide decks of past SF talks and compare them to what was presented in the meatpistol talk. Then you can decide for yourself whether you think this talk was approved or not -- it would be the same PR department approving all the talks, right?. In any case, the facts may come out in the representation, as you suggest.
