Which Monopoly? Are all large enterprises in USA? There are tons of them outside and they will run the open ones and cheapest ones to infer and those are Chinese. I run Chinese models at home and don't bother with cloud. If I could call the shots at work, we will switch 100% to Chinese models so everyone could have "unlimited" tokens.

You might be underestimating how significantly cheaper this is and how much people care about price.

Walmart is a horrible company owned by horrible people and yet it’s cheap so it dominates.

If the quality really is in the Opus 4.6 range (considering how bad 4.7 is), then it’s a pretty big deal.
