To be clear, this isn't a product called "Presenter", this is a person who works for Microsoft who switched to Chrome during a presentation. Nothing to see here.
It's a little embarrassing though. Had they at least chosen Firefox which isn't a major competitor of theirs across multiple markets, it wouldn't be nearly as bad.
If he'd tried it in Firefox next I think everyone would have been distracted by the question in their heads of "does it not work on Chrome?".
