You can buy other mice and keyboards, even the gamer type, without pushy dark-pattern crapware, if you avoid certain brands, e.g. Razer. Anyway, I think they're roughly right about gpu driver bloat. Release frequency has a lot to do with new app-specific optimizations, in between updates to support new hardware configs. As far as size, even without the GeForce experience-type stuff, the packages are still huge. They're supporting multiple generations of complicated devices with a sprawling set of features and APIs, but it's also those host hardware and app-specific tweaks building up.
