Of these eleven articles, ten of them run against Amazon, its business model, or its affects on society either directly in the headline or in the tagline listed on her author page...the only one I could find that didn't was "Free Shipping Isn't Hurting Amazon" piece.
So, as a person who had written a bunch of articles in the last 7 months criticizing Amazon, did that color her expectations of her Amazon Flex experience? It seems pretty clear she took the job so that she could write the piece, even basically admitting at one point that she was carrying around her reporter's notebook while on at least one of her Flex runs.
I doubt she made any false statements, but along with the objective statements, she included quite a number of subjective ones which clearly supported a thesis of "Amazon ruthlessly exploits the gig economy". And a significant portion of the article was dedicated to her own "tech support" issues...none of which seemed to be supported by quoted observations from the people she interviewed.
I don't doubt that there are valid problems and criticisms of Amazon Flex. I just don't know how much I can trust this article to objectively communicate them.
