I don’t care whether you personally care about your game saves

Exactly, nor should you. I'm just stating that I personally don't care, so I'm not going to boycott Nintendo or something over it.

That said, I very much do believe individuals should actually own the hardware they buy, and I'm fully supportive of efforts to root their devices. I believe strongly in Right to Repair, and I believe customers should, at minimum, get documentation about how to repair their devices (i.e. board level schematics, part lists, etc), as well as no blocks from the vendor for manufacturers to sell parts. There's a good chance that this type of information could help people root their devices, but as long as the vendor is commercially supporting their platform, I don't think they should be obligated to provide source-level details (I'm buying the hardware here, not the software). But once they stop supporting it, they should be obligated to provide information about how to load alternative software onto the device so customers can continue supporting their own hardware.

Nintendo gets away with it because the laws protect them, and even obligate them to aggressively protect their brand. Those laws should certainly change. However, as long as they provide a product that provides value to me, I'll get it. I'll do what I can to mitigate issues though (e.g. I'm shopping for a new car, and I intend to remove/disable the chip that communicates w/ the manufacturer).
