They don't block any apps. They just remove the ones that do not abide by the rules. Also Google is pretty liberal itself and likes free information (Well, they are a search engine. of course they do) and I do not think they would remove it even if it would say "And this is why democrats suck" in big-red letters on every report. You are free to use the app or to not use it. It's your decision in the end.
