Either you missed the point of that survey or you're deliberately misrepresenting its results. Did you miss the sentence that said 'This ranking is determined by share of "a lot" responses.'? Amazon is the 2nd most trusted brand, according to that survey.
I might have translated that survey result more into something like “No major brand deemed trustworthy by majority of consumers. Amazon a little less distrusted than most other major brands”.
I can't find anything specific about the survey methodology related to this data, but there being an 'a lot' response implies to me the existence of answers like 'a little' as well that convey trust
