"Less is different -- small groups of people can engage in kinds of interaction that large groups can't. And so we blew past that interesting scale of small groups". Leopold Kohr thesis (such as "Below a certain size, everything fuses, joins, or accumulates. But beyond a certain size,everything collapses or explodes") are pertinent.
I suppose that (quasi) monopolists like Google, Amazon, and Apple are still to small for that thesis?
