Despite all the rough and hard times bitcoin had suffered from US i can tell you vividly that US is still one of the countries with the highest numbers of bitcoiners in the world, yet it government attacking to regulate the currency, but your comparison here is what may be confusing because I don't see any correlation between bitcoin and speech, if bitcoin had been considering all manners of speeches against it maybe it could have been nowhere today, everyone has the freedom of speech while bitcoin remains unltared by any level of human speech lavied against it.
