They'll provide "tools and manuals". If this includes service software that is good. Also I wonder what kind of detail is there in those service manuals. For the mechanical components I would at least expect drawings of each assembly showing every gear, every seal, every clip with spec. For electronics I would expect at least board view files if not schematics. Do I believe this will happen before it is law to publish it? Not really.
When finally those laws get proposed I fully expect manufacturers to claim "security and IP theft" exceptions and politicians will fold. I still have electronic equipment made in the 80's that had not just schematics in its manual, but pcb layout drawings so you could remake a pcb if it got destroyed... And somehow we didn't have clones of this equipment appear.
