Yes. Not only censorship, we also have the Great Firewall. You use Facebook, we have QQ Zone. Twitter? We have Weibo. And Baidi for Google. We have cloned most of the world-famous websites.
But things should not be like this. That's why we are so excited when we met Steem. Even steemit.com is blocked in China, no problem, because it's true decentralized platform. Nobody can stop the Blockchain.
Everybody should be born equal to get information.
@somebody nobody can stop the blockchain, but chinese gov can stop people who use this. And force them not to. That's quite simple to understand. What you post on blockchain will stay, OK that's right, but first you need to be able to post (if they dont block all IP / nodes/ access), then if you do, it can be illegal for you soon or later if they decide that it should be.
People can go in prison for doing this, so Nobody can stop the blockchain you're right, but people can be stopped very easily.
People went to prison because they post something anti-government, not post on facebook or steemit.
