Pastebin, Dailymotion, GitHub Blocked After DoT Order in India

Why? I can't think of any reason that makes banning these products a rational move. Do they want code snippets from Indian developers to be hosted by an Indian firm? This is just bizarre.

Why would they ban Dailymotion, Imgur and Vimeo? Lewd Content?

There is a way to get around it.

Use the OpenDNS IPs: 208.67.222.222, 208.67.220.220 for your DNS.

What must be the reason to block Github?

It seems that after a government deploys mass surveillance, mass censorship comes "natural" after that, probably because they start finding out what their citizens are really doing, and they don't like it. So they want to "fix it" by controlling what they can watch or do. They just can't help themselves.

We need more decentralized surveillance and censorship-resistant systems. It seems to be the only way to stop this. "Democracies" don't seem enough to stop this at the political level these days. It's just too easy for the governments or parliaments to pass orders or laws such as these, and it's much harder to mass mobilize against each one of them.
