Think back a minute to the definition of a rentier: someone who uses their control over something that already exists in order to increase their own wealth. The feudal lord of medieval times did that by building a tollgate along a road and making everybody who passed by pay. Today’s tech giants are doing basically the same thing, but transposed to the digital highway. Using technology funded by taxpayers, they build tollgates between you and other people’s free content and all the while pay almost no tax on their earnings.
