The point was that Rossi will be given absolution for his "somewhat unsavory by modern standards" bisiness practices. Rossi will eventually be recognized to have made tremendous contributions to both technology and basic science. That is just the way things roll.
No one is given absolution for unsavory practices. No serious biography excuses or glosses over Edison's behavior, or Oppenheimer's for that matter, or anyone else's.
Rossi will not be recognized because he has not made any contributions. His claims are lies and frauds. You believe him because you refuse to read his reports, look at his data, or look at the photos showing the heat exchanger did not exist.
