No need for actual free speech. Host it in Russia, China, Venezuela, Iran, DPRK, or any other strategic adversary of the United States. The success of ICEBlock is 100% inline with their information warfare goals. The more strife they can spread, the more protests, the more violence, the more confrontations, and the more 'noise' that gets made about ICE in the US, the better for them.

That doesn't mean the developer of ICEBlock is anti-American, just that there's a common interest in seeing his project succeed.
