Here is the reason not to send materials to people in advance of a presentation: “If I send them all of my content, they won’t need me, they won’t be impressed by me, they will be ready to poke holes in my data, and they will have ammunition to use against me. Better to keep them in the dark!!!”

That’s the reason I use here, but it’s just not a good reason.
