I never once said I was against regulations, but time and time again regulations have had to be dialed back because, in America, you can't unduly impose costs on a company without clear, measurable public benefit that outweigh the costs. Companies are free to choose how they do business. If apple doesn't want to be in the supporting the third-party repair shop business I think it's going to be hard to argue that that should be. Would it be fair to force you to be in a business that you didn't want to be in? These parts everyone thinks should be cheap and available, have to be designed, manufactured, documented, inventoried for years, paid for upfront by somebody and distributed individually through some reseller channel or network when somebody wants to buy a single unit. And everyone seems to want this at some wholesale cost that will undercut a company's first-party repair service. So basically you are demanding a company be regulated to compete with itself and foot all the costs in doing so.
The argument that that this saves e-waste from the landfill is bunk as most consumer electronics are disposed of not because they are in disrepair, but because they age out of usefulness. Forcing companies to provide OS support for older devices would probably do more to solve that problem than allowing consumers to save a few bucks on a battery swap or screen replacement, but that's not going to happen either. Apple has a good faith argument that they do provide repair services on their products for years after they are sold. The bad-faith argument is that they should be forced to undercut that service to allow consumers to get cheaper repairs on products they paid a premium for.
