To me it is clear that Gates was prepared by a host of lawyers, which makes sense.

But the interrogator doesn't grasp the subject entirely as well, I too would want clarification to the question if a content provider uses IE. You could ask a helpful question, e.g. Do you mean if they develop sites specifically for IE?

But That is not how you go about a deposition, you're not there to help people build a case against you.
