This should indeed be reported as illegal product tying to regulators (U.S. FTC/EU Competition commission/others?) so that Apple is legally deterred from breaking this interoperability effort with future AirPods updates.
It's basically the consequence Google v. Oracle and the cases leading to it.
Product tying is not a thing you can bypass.
This is idea is independent of whether Apple’s strategy is good or bad, legal or not. Product tying can’t be undermined, or it’s not actually a problem.
