Don't think this kind of thing is new, rare or shocking.
Peter Thiel in Zero to One also gives examples of how a company can be considered a monopoly and not a monopoly by simply increasing the definition and size of the market that the company is operating in. (And how companies will generally try to avoid being classified as monopolies this way)
e.g. Google is a monopoly if you consider online advertising as the market, but if you stretch the market to all advertising (including print, radio, TV and billboards), Google might not be considered one.
Similarly Amazon in the e-commerce market vs general retail.
