"This block was the result of a communication error between Zoom’s domain registrar, Markmonitor, and GoDaddy Registry, which resulted in GoDaddy Registry mistakenly shutting down zoom.us domain. "
Something is fishy about this. A communication error would not result in a domain being placed on hold. On hold is usually the result of a legal order or in the case of the .us TLD a nexus compliance violation. I've transferred thousands of domains from assorted dodgy registrars into MarkMonitor and can not even imagine a scenario where a miscommunication results in a domain being placed on hold.
If there is a "default" then "everything else" is not weird. The conclusion is "this thing doesn't work most of the time so it wouldn't be weird if it doesn't".
