That is a presentation to the outside. Internally, PowerPoint gets almost zero use. Everything is document+appendix based. There are exceptions for things like org level meetings and announcements that are more of a broadcast medium but anything that is collaborative or at a smaller scale is done through a rather ridged standard document format. Overall, there isn't a ban on use but it has a very limited use compared to many other companies.
