> "Monopoly" used to mean a single company controlling a market. Now folks are now hollering "monopoly" about five different companies competing and collectively capturing 90% of a market?
Five companies controlling 90% of the market is more than enough to form a cartel or spontaneously self-organise in ways that have the same effect even without explicitly coordinating. (I once read an economics paper that I wish I could find now that said this would happen when the top 4 companies in an industry controlled more than 60% of the market)
