I think you are missing the word "unfettered." It's the difference between an expertly manicured garden and an unkempt one. Someone has to do the weeding, or it will be all weeds. You may say that whoever does the weeding is practicing censorship, but that doesn't mean it's an unnecessary job. Yes, it's difficult (and morally hazardous) to decide what constitutes a weed, but the alternative -- not weeding -- is worse.
