Financialisation and capital accumulation allow tremendous inequalities in allocation. These have always been present to some degree, but recent history (say, 1800 - present) seems exceptional. Note that arguably the Gilded Age personal fortunes were probably even more extreme than those of today.
Unless I'm missing something, the marginal cost of software publishing is very near zero. Development is ... more expensive.
The Internet's role is a whole 'nother discussion, but pulling in a notion of an ontology of technological mechanisms (see: https://ello.co/dredmorbius/post/klsjjjzzl9plqxz-ms8nww), it's a network, with network effects, as well as a system. These ... tend to define general parameters and considerations.
Where specific industries fall on the mediocristan / extremistan scale .... is an interesting question. Though I'd argue that systems/networks elements tend toward extremistan. Whether hardware is/isn't systems/network (as I'm using the terms) is another question.
For successful fundamental component manufacturers (e.g., Intel, AMD), hardware certainly resembles extremistan.
Just FYI; You might want to look into the works of Jacques Ellul on Technology and Society if you have not done so already.
