ICANN didn't create any of these new ones; registry operators who applied for them did. It's a crucial distinction. I guess you could argue that ICANN should've limited it somehow, but ICANN picking and choosing the haves and have nots like that would be worse than the current situation, where pretty much anyone who wanted to could get whatever string they wanted (subject to some reasonable restrictions).
