I don't believe in the Right to Repair absolutely. I don't think Apple should be disabling functionality for using third party parts and I think the battery in Macs should be easily replaceable. Apple can use similar adhesive to the adhesive used in the iPhone for the Macs' battery. You shouldn't have to remove the entire logic board to replace the battery. Diagnostic software and schematics should be provided by Apple because they're already available through unofficial sources on the Internet.
Right to Repair is a marketing myth.
You have a right to do mostly whatever you want to do with your property. I mean, you can't take your iPhone and beat someone over the head with it, but you get the point.
This is a market issue. The market moved on to thinner, lighter, sealed, etc.
The majority of people don't worry about this because of the majority of users know nothing about their RAM and don't consider battery swaps anymore for their phones. This is just the way things are.
Now, people become concerned when they realize they have to buy a new machine because of what used to be a routine and cheap part going kaput. But realistically, given the number of users, how big of a concern is this to most people?
Hey, I wish I could add RAM to my Mac. I wish I could work on my car myself, as well, sort of as a hogbbyist.
But I don't have a laptop from 2002 and my car is not from 1968.
I will always be on the side of right-to-repair and I hope things change at Apple regarding this issue. I would not object even to (limited) government-action on this issue.
My current Macs are from 2011/2012 where RAM and drives aren't soldered. I stopped buying Macs back then because of this.
That said, I have completely given up on Apple making things repairable/upgradeable after ten years of waiting.
I know full well Apple products are sealed and I came to peace long ago with the fact that:
A. I will have to accept whatever cost comes along when my device breaks
B. Apple Care is no longer optional
C. Keeping the device past the warranty period is an ever-increasing risk; Selling/trading-in an out-of-warranty device is now a requirement
This is the cost of admission into Apple-land folks.
Each of you must decide whether or not it's worth it.
@Darth Tulhu gets it. Not just Apple stuff either, although there's more freedom with Windows part swapping, I guess.
