This is incorrect. For example, "Our Model S never had a chance with John Broder" is an assertion. "Vehicle logs tell true story that he didn't actually charge to max & took a long detour" is an assertion ("long detour") and one that Musk backed away from. There are also assertions in the original post that Musk's data didn't address. For example, Broder said that a Tesla customer support agent gave him inaccurate information about appropriate driving patterns for maximum range. Broder may or may not be accurate there but it's certainly an important part of the argument.
