“Embrace, extend, and extinguish”,[1] also known as “Embrace, extend, and exterminate”,[2] is a phrase that the U.S. Department of Justice found[3] was used internally by Microsoft[4] to describe its strategy for entering product categories involving widely used standards, extending those standards with proprietary capabilities, and then using those differences to disadvantage its competitors.source
