Acquiring your competitors to kill competition isn't a "good move," it's an obvious strategy that has existed for hundreds of years and is (rightly) illegal.

We unfortunately forgot the lessons of the Gilded Age in this country, and incredibly anti-competitive acquisitions like that have been tolerated on too many occasions.

It's easy to make "good moves" if regulators are ignoring you and you're comfortable with being immoral, as Zuckerberg always has been.
