The example is of course egregious ($600 for a software update for a wire that got wet, basically). I fully support being able to repair your own stuff but I have no idea how you regulate this so companies don't gouge "owners" for aftermarket services. Earlier today there was a thread about e-bike battery prices (tl'dr they're ridiculous expensive). I really wish rechargeable batteries had interchangeable form factor…
This is my concern too, but, I think way more broadly than you.
I love the idea of right to repair. I agree on a fundamental level, this is your device, you bought it, you own it, you should be able to do with it as you please.
What I don't agree with is creating additional regulatory or legislative burdens on companies. I have a number of concerns with doing so, but, philosophically I don't see it as the government's right to unduly interfere in apple (or samsung, or john deere's) right to sell me a product I want to buy.
More directly, I am worried about right to repair stifling innovation and competition. I could easily see a regulatory body require all phone's have user-replaceable batteries and that is not something which I fundamentally want in a phone. It has tradeoffs which I don't want to make.
That said, I think companies like Apple refusing to sell genuine replacement parts at any price is egregious.
However, I also think the government forcing private companies to disclose things like engineering or repair manuals which contain secret/trade information is equally egregious.
All of this is a long way around to saying that while I love the concept of right to repair, the devil is in the details and I haven't seen anyone really enumerate the details of what they'd actually like to put into law.
Am I wrong and is there anyone with actual proposed legislation?
