Earlier quoted context omitted.
I said "monopoly rent." It's a term with a specific definition that you would do well to understand.
Pretty much any definition of "monopoly rent" I've found does actually require the existence of a monopoly. Also, there's no reason to talk down to people. https://en.m.wikipedia.org/wiki/Economic_rent#Monopoly_rent
Monopoly is defined loosely and based on the idea of market power, not being a sole provider. The Wikipedia article you cite even mentions Microsoft and Intel as examples, and they had less market power over their fields than Facebook does.
