Sure. Basically, it all comes down to whether or not you trust the government to be good, always. If you believe this is the case, you're fine. If you don't, you will probably prefer un-censorable technologies. America has (historically) tended to fall pretty far to the "free speech" side of the line, though there is a push to change that.

Even if you trust the American government, people in repressive regimes can still make use of this. This could enable a western news outlet to make itself accessible to those who are brainwashed by state media.

Trying to prevent "hate groups" from congregating or criminals from opening marketplaces doesn't usually work, either. It's the prohibition principle: if you ban the tech, criminals will use it, but an American NGO won't be able to reach those with censored internet.

You may not use it, but I don't see why your "being on board with it" ought to affect what others create.
