This is a lot of words to describe rent seeking. Google, Amazon, Instagram/Meta, ultimately all of these are earning their outsized margins through market-dominance enabled intermediation of commerce. I search for 'foo' and the top result is either Foo paying through the nose for what should really should be organic traffic or Bar 'buying' the click instead. In the absence of anti-trust the only winning move is to buy stock in the monopolists, their ability to extract these rents from an ever-growing proportion of the economy is only getting stronger.
