I think it might be more about how much contact your keyboard has to particulates. The primary mode of failure has to do with dust/crumbs/etc getting into the mechanism. It's not impossible to imagine that people who type in more particulate-rich environments have frequent keyboard issues. But that's still victim blaming. There are plenty of keyboard designs which are not this fragile, and you shouldn't have to dust-proof your workspace to avoid hardware failures. We're not making CPUs here.
