The 2011 ones were even easier than that. You pressed a lever then half the bottom case came off, exposing the hard drive and battery. The battery came off by just pulling a plastic tab, the hard drive had a couple screws iirc. The 2012 one that I'm typing on now requires unscrewing the bottom case, but still everything is right there behind a couple obvious screws and you can upgrade RAM/HDD/battery/replace disc drive with second hard drive in 20 minutes if you are working slow. I knew it was the beginning of the end when the 2013 macbook shipped with soldered RAM.

But ultimately it does not stop those who want to try. I don‘t see a problem. Will this right to repair revocation put those who attempt in prison? What‘s the underlying problem.

Look, I bought a new car. It comes with cameras in the bumper. It made replacing a damaged bumper inherently more difficult for an average Joe. It doesn't mean though that it is impossible to replace it without visiting an authorised service centre. Same logic.

The "spare" parts come from donor boards that are obtained via unsanctioned back channels. Authorized repair shops are generally not allowed to actually fix anything. Instead they tell you it can't be fixed, your data is gone, please buy a new device.
