This smells like something happened with MarkMonitor, they accidently flagged zoom.us as brand spoofing and filed copyright complaint with GoDaddy who runs .us TLD. GoDaddy suspended the domain per the complaint.
It's possible, but MarkMonitor is Zoom's registrar, so there are plenty of other ways for a miscommunication between MarkMonitor and GoDaddy to cause this. Copyright complaints would be a more reasonable theory if MarkMonitor were mentioned and didn't have any other involvement.
At one point on a trip to Hawaii I was detained in my room by hotel security for fifteen minutes after requesting a room key to replace the one I lost.
It turns out that they had typo’d 12 into the request type field instead of 1, and type 12 was “Covid lockdown protocol with security enforcement” leftover from 2020 and latent in their systems.
Depending on MarkMonitor have chosen to integrate with each other to handle the sort of trademark management that is MarkMonitor’s premium offering, either or both parties could have simply been off-by-one or typo’d in a transaction to cause this. It’s absolutely plausible to create a confusing nightmare outcome with a one-byte error. (And we’re having quite incredible cosmic rays today, so I hope they’re using ECC RAM!)
If this is the case, then it seems to be a very clear-cut example as-to why we should reject these sort of automated "take downs". They can and are abused, including copyright violations on Github, YouTube, etc.
Since when did we accept, as a society, guilty until proven innocent? I recognize GoDaddy is not the government - but this is unacceptable. A human spending 3 seconds looking at the domain would understand it's a false-positive and should not be removed.
