Maybe I am missing something. As an owner of device or equipment, being able to repair is very basic right to the property. Why is it a big deal? Would love to be enlightened.
You can have a right in principle but companies must actively take measures to make parts and documentation available for it to
actually be possible to avail yourself of that right. The big deal is over which purposes and to what degree governments should be able to compel companies to offer this to their customers, support resale of used parts, support business that broker parts, etc. There are a lot of messy details and tradeoffs.
