Berkeley, Calif.

WE who love the Internet love the fact that so many people contribute to it. It’s hard to believe that skeptics once worried about whether anyone would have anything worthwhile to say online.

There is, however, an outdated brand of digital orthodoxy that ought to be retired. In this worldview, the Internet is a never-ending battle of good guys who love freedom against bad guys like old-fashioned Hollywood media moguls. The bad guys want to strengthen copyright law, and make it impossible to post anonymously copied videos and stories.

The proposed Stop Online Piracy Act, or SOPA, which is being considered in the House while the Senate looks at a similar bill, is deemed the worst thing ever. Popular sites like Wikipedia staged a blackout on Wednesday to protest the bills. Google put a black banner over its name. Nothing quite like that has ever happened before. This is extraordinary, because it shows that belief in the priority of fighting SOPA is so absolute as to trump the stated nonpartisan missions of these sites.

The legislation has indeed included draconian remedies in various drafts, so I join my colleagues in criticizing the bills. But our opposition has become so extreme that we are doing more harm than good to our own cause. Those rare tech companies that have come out in support of SOPA are not merely criticized but barred from industry events and subject to boycotts. We, the keepers of the flame of free speech, are banishing people for their speech. The result is a chilling atmosphere, with people afraid to speak their minds.
