>> And shame on the government for not doing any due diligence in trying to prevent this acquisition/monopoly.
> Monopoly? In 2012, Instagram had 40 million users and no revenue[1]. Hardly a monopoly.
I think you misunderstand. Facebook is the monopoly in the grandparent, not the independent Instagram.
I believe the GP's point is that the government should have blocked FB's acquisition of IG, so IG could have provided competition for FB.
