It's very common. From a certain level up, execs rarely use the products they are responsible for. It's all about strategy, committees, meetings, plans and reports. For them the product is just an abstract thing. When I rented a Buick car, I thought to myself that there is no way any decision maker ever tried the car and thought that this is ok.

I think one of the strengths of Apple during the Jobs days was that Jobs actually sometimes seemed to use the products himself and gave feedback. When I look at the blatant bugs MacOS and iOS had in the last years, I also think that the current Apple big shots never use their stuff or they would have noticed.
