This is false.
First, Amazon is far from controlling the whole market. They control close to 50% of e-commerce which itself represents less than 12% of total retail sales.
Second, Amazon didn't predatory price, or if it did, it didn't for long, certainly not long enough to achieve its current market share. The author is mistaking Amazon's lack of profit for its propensity to reinvest all of its profit into other businesses (e.g. AWS), or its willingness to take short-term losses in order to reach economies of scale where profits exist (which, as Amazon's retail business has shown, they do).
