I enjoyed the tone of the comic, however, even if it was inaccurate or disputable or at times just plain wrong. For me, Edison is one of those figures, like Christopher Columbus, or George Washington, that you learn about every single year growing up, since kindergarten, and whose myth is so grand and ubiquitous that every teacher I had from elementary school up until junior year physics said the exact same thing about him. Tesla was just another of a dozen names in the textbook.
So in a way I understand the sentiment. You grow up being told that this is guy, Edison, is the most awesome inventor in the history of America. And because of that I always felt a certain distrust about his accomplishments (even if I'm wrong), because so much of what my teachers taught me growing up turned out to be wrong.
