I think that some people don’t think that Edison did anything wrong because they have more of a business attitude rather than an ethical attitude. Ethics can sometimes get in the way of making money because sometimes companies act ‘grimy’ or ‘dirty’ to get what they want. Some companies can try to undermine other companies like Edison was trying to do, by trying to give the AC system a bad connotation to drive them out of business. I believe if your product is good enough, you dont need propaganda to demote other products and glorify yours. Bad ethics may sometimes be good business but good ethics allows you to sleep good at night.
