I understand the author's preference, but as a seasoned presenter and veteran audience member I must say I do not share his opinion. Sharing slides before a talk can be useful, but only if the slides are mostly bullet points and diagrams. If otoh you use a more empathic/media journey style of presentation materials, there is little point in doing this or even negative value. The most boring form of video presentation I can imagine is a talking head. Trust me, you are not that pretty, nor do you have the facial gymnastic entertainment level that I want to look at you for half an hour in closeup while you command me to turn pages. Show me something interesting on the screen, maybe cutting to you for 10-30 seconds when you want to emphasise something. Get a greenscreen and OBS if you want to go a bit further. Overlay yourself on the presentation if you want. If you are presenting, you are not just 'relaying information', just write up a briefing/memo/paper or email if that is your goal. In a presentation you have to capture your audience, entertain, and yes, inform.
