Blame methods not tools! This has nothing to do with PowerPoint. This is about bad or wrong methods of presenting ideas or concepts. Methods are how something is done, e.g. graphically by a diagram or textual in short form or by speech. PowerPoint is just a tool. You can use the wrong method of presenting an idea (e.g. graphically) with a different tool (e.g. a sheet of paper and a pen) as well.
