There is neither anything inherently wrong with PowerPoint, and even more 'controversially' there is nothing inherently wrong with information dense slides. Especially in the case where it includes complex graphics such as maps and charts as shown here.
The small information limited bullet point laid out form of presentation is derived from marketing/persuasive presentations. In that context then yes the narrative should drive the discussion, and slides should just reinforce the 'take away' points. These slides should be light for the same reason Elevator Pitches should be less than 2 minutes.
However other presentations such as some of the ones shown in the article are not intended to persuade but intended to share dense information. For instance saying that the military should not put dense maps in presentations intended for brass who have to visualize the geographic layout based on the presentation is pretty clueless.
Its a tool, not everyone is using it to accomplish the same goals as the author is. Truth is 99% of times the marketing format of presentations is the way to go, but it is not 100% of the time.
