Good. People should always have the option of fixing their own property without repercussion. If the disk drive fails on an Xbox it's a simple process to replace the part, same goes for things like fans, USB ports, switches, etc. There is no reason anyone with a working brain shouldn't be able to do these simple repairs if they want to. I'll always encourage people to learn to fix the things around them as it's often a lot easier than they think. The average Lego kit is actually more complicated than taking apart a TV, PC or even a car engine. A Lego kit has hundreds of parts that can fit together any way. The parts in an Xbox only go back together one way. The same goes for PCs, a toaster, an electric trimmer, and the engine in a car.
I fix everything I own myself. Electronic devices can be repaired for a tiny fraction of the cost of replacing them outright. I'm currently repairing my 4k monitor which started losing it's backlight after 6 years of constant use, it will cost me $12 in parts and a half hour of my time to repair and then I can sell it for $400. If I sent it in to get repaired it would be about $150 to get done where I live. I've repaired controllers, replaced screens in portable systems and torn down many other devices. There are an incredible amount of resources available these days to walk people through the steps of how to and how not to repair just about any device. Sites like Ifixit have detailed step-by-step teardowns that are free to use.
I've been fixing my own vehicles for a couple decades now because dealerships and service departments constantly fucked up things as simple as an oil change or claimed to do work they clearly did not (I've caught them). I can pay $800 to replace the struts on my winter beater at a shop, or I can buy the struts for $100, a spring compressor for $30 and do it myself in a couple hours with basic hand tools. I essentially paid myself $670 for a couple hours of labor.
Good on MS.
Think of it like fixing a car. You don't have to bring your car to the official dealership brand. Whether it's under warranty or out of warranty, you can bring it to whomever you want. You are allowed to also open up the hood or put it up on a jack and look around yourself. No car company says "Hey, we can tell you were poking around under the hood so were voiding your warranty". Maybe if you went ape shit and totally messed it taking it apart they'll say no. But you can still reasonably fix things yourself or through a mechanic while still maintaining warranty.
And you're also allowed to buy non-OEM parts. Toyota doesnt say you cant repair something unless you use an official Toyota part. Hell, if you took you car to a Toyota dealership to fix, they might not even use an original part either.
You get your thing fixed, the repair shop makes some money, and everyone is happy.
But somehow, some electronics have this stonewalling effect where only they are allowed to fix.
The problem is the dealerships that sell people the new cars skirt the laws a bit and use wording that has them believing they have to get their work done there even though they don't. I can't even count the people I know that dump $120+ on an oil change because "We have to for the warranty". Meanwhile I spend $30 to do it myself. The automotive industry would love to rip you off, the issue for them is that they have met with strong legal opposition. In the US for example the Magnuson-Moss Warranty Act basically turns manufacturers vague wording against them and the burden of proof falls on them if something fails on your car under warranty. If I put a new intake on my car and the rear diff fails, the manufacturer can't correlate the failure to my work so they can't deny the warranty. A lot of countries have similar rules.
The issue is that electronics repairs are a much more varied market and a legal solution is harder to reach as new devices are constantly popping up while cars have remained almost entirely unchanged for decades. While individual vehicle components have improved and changed, they serve the same functions and attach to the car in the same way they did going back to the Model T. Electronic devices are different year-to-year and as a result often come and go before RTR advocates can even get the ball rolling. Right-to-repair advocates are making headway though and the result is RTR advocates finding their way into investor meetings where they can voice concerns and into the legal system where they can shape regulations around RTR.
I really think kids should be taught how to do basic maintenance and repairs to electronics in school. We had a high school shop class in my home town, but we were never learned anything useful that could be applied to our life after school like basic automotive maintenance or the basics of electronic repairs.
