Yes, but that still represents a very serious problem. The EFF has written extensively on it since this occurred in August. Here's a starting point: https://www.eff.org/deeplinks/2017/10/eff-icanns-registrars-....

ICANN has worked very well so far, but if they don't put up a strong response to registrar-based censorship on already-registered domains and make this contractually impossible, the internet is going to be in big trouble. We can't let "you can't have a domain because we don't want you to be able to talk, as a matter of corporate policy" become a thing.
