ICE/DOJ have been committing all sorts of nasty prior restraint. They got away with domain seizures against innocent websites simply accused of hosting copyrighted content. Over a year later they return the domains and don't even apologize. (Dajaz1.com is a great example of this.)

Prior restraint is one of the worst constitutional abuses with regards to the first amendment, because it causes irreparable harm. Hopefully defenses can be made in the courts against this behavior.

Likely in this case, ICE simply intimidated GoDaddy, which is a terrible company in the first place.
