This is a flawed comparison because the use cases for the former examples are very limited in comparison to USB C which is arguably evolving rapidly still. You could imagine if we had formed such a standard around USB A in the 90s and how it might have blocked the already high friction establishment of USB C and thunderbolt 3 standards. USB C currently seems more mature than USB A, so I can see where things ar ea bit subjective here, but it's not really possible to see where unrestricted development would have put us. I think I would have been more comfortable with simply banning lightning and micro USB than restricting to only USB C.
