The anticompetitive move would be not running their software if ‘which codex’ evaluated to showing a binary and then not allow you to use it due to its presence. Companies are allowed to set pricing and not let you borrow the jet to fly to a not approved destination. This distortion is just wrong as a premise. They are being competitive by making a superior tool and their business model is “no one else sells Claude” and they are pretty right to do this IMO.

Anticompetitive behavior has been normalized in our industry, doesn't make it not anticompetitive. It's a restriction that's meant to make it harder to compete with other parts of their offering. The non-anticompetitive approach would be to offer their subscription plans with a certain number of tokens every month, and then make Claude Code the most efficient with the tokens, to let it compete on its own merits.
