Somewhat off-topic, but...
I think what most people don't realise is that if physical objects such as PCBs were subject to copyright, it would have far reaching consequences that would be catastrophic for consumer rights.
There is a really important principle known as "first sale doctrine", which most people never heard of, but basically gives you rights to own, use, lend or sell a product once you have legitimately bought it, regardless of IP rights embodied in it. However, when products are "licensed but not sold" then manufacturers can bypass that and impose whatever terms they want on the licensee (customer).
Manufacturers would license all their products instead of selling them. The license terms would be written to maximise profits for the manufacturer, which means being most restrictive for the licensee.
Think you can repair "your" product? Forget it, you must take it to a manufacturer authorised repair centre. Think you can re-sell your product secondhand? Forget it, the license terms prevent resale. Think you can simply lend the product to a friend? Forget it, the license is granted to you personally, and cannot be transferred to third parties.
Unfortunately, we are already sleep walking down this road, and manufacturers are doing everything they can to lock down products. The ideal situation for manufacturers is that they retain all rights to a product, and customers pay a recurring subscription fee for a carefully limited use of a product. Manufacturers do not want a "level playing field", they want it tilted as much as possible in their favour.
Anyway, if component data was copyrightable, that copyright would belong to the manufacturer who created the pin out, or the IPC who define standards. There is no creative element in taking that data and turning it into a file suitable for a specific CAD package.
However, even if the legal basis for a copyright claim is bogus, the threat to sue is real. You would still have to defend it, and a court could find that there is a legal binding contract with terms not relying on copyright that are breached.
Extending copyright to everything could seem reasonable to protect "creators rights", but you need to look very careful at what the consequences of that are, and who would benefit most from that.
