As an avid PowerPoint enthusiast, I found the Times discussion quite misleading. The NASA scientists followed the advice of Tufte, filling the slides full of information that made them impossible to follow. One should not try to give complex ideas in a presentation; rather give an overview of these ideas and leave the messy details to technical articles. PowerPoint makes it easy to give overview talks and hard to give talks full of ugly details, crammed slides and detailed formulas, almost always leading to better talks.
