I take it that third-parties will not get any new freedoms then, and that things like design patents will continue to apply there. I wonder if the law will have anything to say about price-point, if there's no competition.
I was surprised to see no mention of the matter of companies deliberately engineering their products to be hostile to user repairs. I was under the impression that forbidding that kind of thing was the main point of right-to-repair legislation.
(For example, one part of the system might verify that a peripheral has some cryptographic key to prove that it's an authentic first-party part. With this technique, third-party products either don't work, or are set upon by lawyers for breaking copyright law in cloning the key.)
