"Like The New York Times, CNN and network news programs, it [PowerPoint] appears to be neutral, unbiased and free of any leanings one way or another. Just as a hammer does not tell you what kind of house to build, Microsoft would like us to think...that their product is merely a neutral tool. It is faceless, and it is what you put into it that counts.
However, every piece of software comes with its own set of biases and tendencies. The most obvious bias and the easiest to see in PowerPoint, is the Auto Content Wizard, a feature that makes outlines of presentations with bullet points for those who feel they don't know how to make a presentation themselves...
However, there are more subtle sets of biases at work. The way the PowerPoint is structured and the various options provided have not only been limited...but they have been designed assuming, a priori, a specific world view. The software, by making certain directions and actions easier and more convenient than others, tells you how to think as it helps you accomplish your task. Not in an obvious way or in an obnoxious way or even in a scheming way. The biases are almost unintentional, they are so natural and well-integrated. It is possible that the engineers and designers have no intention of guiding and straightening out your thinking; they simply feel that the assumptions upon which they base their design decisions are the most natural and practical. You are thus subtly indoctrinated into a manner of being and behaving, assuming and acting, that grows on you as you use the program."
