The corporate bureaucracy is as much a product of the overall system, and just as much a slave to its incentives, as you or I. Though granted, the level of self-awareness of their role in the system is on average pretty low. With few exceptions, there is nobody at the wheel of problems like these. Worrying about whose fault it is is usually a waste of time.
Why would anyone stop using those standards? You seem very confused about the incentives for adopting standards. Sure, maybe US-driven standards were chosen over other possibilities partly because of political environment, but once you have a perfectly good standard adopted you’re not just going to throw it out because the original author isn’t cool anymore. You don’t need a dominant power to adopt standards.
And for being “slightly political” and “focused on the standards,” your post sure does spend the majority of its time talking about only politics and not about standards at all
