One way to start penetrating right-to-repair would be to force device unlocking after ownership, device payed off, and end-of-life classification by the manufacture.
Next step would be for the manufacturers to require publishing open documents for 3rd party support without having to sign a NDA.
Both of those require reverse engineering. With camera technology being so complex, this is the feature that limits alternative OS usage with continual security updates after the manufactures give up.
Maybe rephrasing right-to-repair as "consumer protection" could help push it through better with less tech savvy consumers.
