>Just buying a simple tool to load game saves and you could have a soft-modded Xbox in minutes
Because that era Xbox was just a PC built form COTS hardware instead of custom HW. You can still tinker just as well today with a PC, or a PC based console like the Steam Deck, why bother fighting with a proprietary console designed to be locked down? What would you gain? Access to a custom X86 hardware that you can buy for cheap on the market anyway?
