Your ISP is not allowed to censor content (as far as I know) because it is a common carrier. Google is not a common carrier, they can do what they want. If Google can do it, GitHub can do it.
Note that I don't necessarily think censorship is good. I just get annoyed when people mistakenly think they have a constitutional right to not be censored.
And I say that where, exactly?
E: Because I can't reply anymore, addressed to ectoplasm's reply to this post:
Because I said "fuck"? If that is seriously against the rules of HN then I do genuinely apologize (and will probably stop posting here so much). If it's just because I viciously attacked your argument, well, I'm actually pretty sure you're a wonderful person ectoplasm, and I am sincere in saying that, but the argument you're putting forward is fucking stupid, and ought to be called such. AFAIK that's not breaking any rules.
E2:
I have a reply link - I've hit some posting limit.
Not only stupid people make stupid arguments. You are probably not a stupid person. The line of reasoning of the argument you put forward here, most definitely is.
> Be civil. Don't say things you wouldn't say in a face-to-face conversation. Avoid gratuitous negativity.
edit: To reply without a reply link, you have to click on the timestamp. Your comment wouldn't be civil even if you elided every instance of 'fuck'. Who makes a stupid argument? A stupid person. You didn't really viciously attack anything, you just said I was stupidly wrong.
edit2: What does it even mean for an argument to be stupid? That's not very convincing. Your arguments are also stupid. So we tie?
p.s. I wasn't really offended or anything, I just think it's good for property rights to trump free speech, and the HN rules are an example of that.
