Wikipedia clones probably got enough traffic to show up on someone's dashboard/report. SO clones are probably a small fraction of all traffic, even though they seem to show up in a large percentage of the searches we perform.
But that's not censorship. Google is not a government, and no one's speech is being suppressed by filtering out literal copies of something and leaving the original.
Change the flag button on this post to censor and I bet people wouldn’t click it. But people want some level of censorship, so long as they convince themselves they’re not against free speech.
Blacklisting by a private entity is not censorship. It's even sillier when you consider that what's being removed are copies and the original content is still there.
