Actually, that source quotes the Feist decision. The rest of the discussion makes it pretty clear that domain registries are not copyrightable. 

“Thus, a database of unprotectable works (such as basic facts) is protected only as a compilation. Since the underlying data is not protected, U.S. copyright law does not prevent the extraction of unprotected data from an otherwise protectable database. In the example of a database of presidential quotations, it would therefore not be a violation of copyright law to extract (copy) a quotation from George Washington from the database. On the other hand, it would be violation to copy the entire database, as long as the database met the Feist originality and creativity requirements.”

The key problem is that no domain registry meets the originality and creativity requirements set forth by SCOTUS in Feist. 

I am not a lawyer either, but I have a lot of initials after my name, just like some lawyers that post on NANOG :)

I don’t think copyright can enter into it, by dint of the fact that registry data, being purely factual and publicly available, cannot be copyrighted.

I'm not a lawyer nor pretend to be one on the internet but https://bitlaw.com/copyright/database.html provides some nuance to that statement.
