It’s not the right of the business, it’s the right of US citizens to consume media and information from any source they please. The Govt has no right to say “You can’t read that newspaper” or “You can’t listen to that speaker”, so they have no right to say “You can’t get information through this app”. The first amendment isn’t just about the right to speak, it’s also about the right to listen and research especially the stuff the government doesn’t want you to know about.
