Earlier quoted context omitted.
> When a company can loose money on a competiting company just to drive the competing company out of business; I call that a monopoly. You can't just redefine what words mean if you want to be taken seriously. Especially when what you described is a legitimate and very common business tactic [1] [1] https://www.investopedia.com/terms/l/lossleader.asp
When it's done to force competitors out of a market it's called predatory pricing [1], and it is not a legitimate business tactic. It is illegal in many jurisdictions, and generally considered unethical even where it's not specifically outlawed. It is also considered a strategy to achieve a monopoly or near-monopoly pricing.

That only applies when one of the competitors is effectively a monopoly anyway.
