Restrictions on speech, specifically with NSLs, can happen to only a few people but still be extremely significant. The example of the Lavabit email hosting service comes to mind. He was served with an NSL requiring him to nefariously gather the private encrypted emails of his users. He was a single person with an extremely important thing to say with drastic implications, but was legally barred from doing so. I would call that significant. Multiply times thousands of people and you have thousands of very important things being censored.
