Sadly the right to repair movement has been slow to work for humans. You really need to stick with the proprietary OEM parts, but MomCo refuses to provide them as "impossible". There is some hope in bio 3D printed replacements reusing the cellular DRM recovered from a specific unit though.
A jailbreak to resolve the DRM and closed-ecosystem issues is always supposedly 10 or so years away, but like economically feasible fusion I am not sure I'd count on it any time soon.
That's what all the street grime is for, making the mud wallow.
