The anti-Capitalists on the Free Republic (believe it or not, they do exist) absolutely hate Edison for how hard he drove his people. Anti-Capitalists are wussies. To heck with them.
All I know is that Humanity will never be able to repay Edison for all the good that he has given to us.
I understand he was a prickly character at times (just read his Wiki bio) with an ego (understandable). He resorted to dirty pool with the AC-DC debate.
However without his contributions we might not be communicating in this manner.
