How would you even start to enforce those laws against a company that no longer exists? It’s one thing to prevent the AI companies from selling a product that relies on continual support in the first place, but these earbuds will work until the batteries degrade (and theoretically longer if you can manage to replace them without destroying the things) with or without the company’s existence. The fact that the user lost the case with no company to replace it doesn’t seem to me to be the kind of thing that you can really address legally, unless you make the companies put a certain stock of parts in escrow or something, which seems potentially clear more wasteful than the status quo.
