In this interesting article"Chinese YouTubes Courting controversy?" by William Moss. The author talks about how the world has changed since the last decade until now, he assert that this change incorporate the technology system with our life. Moreover, he talks about kind of technology the government try to control it, which is Internet. The author declares the government side and they have the right to block some websites in the Internet. In addition, he verbalizes an important question about Chinese government and they can block anything they find it against their policy.
If we begin our discussion by do the government has the right to block anything the want, in my estimation they cannot do that especially in country as China. Country of 1,317,411,509 and still increasing,see here, have the right to choose what they want to watch. In addition, if we compare between china and any another country in the technology system, China still behind in some parts because the Chinese government still anxious from technology and specially network system. Thus, they block websites one after another. However, youtube`s revolution in the network made all people around the world between our hands, we can see them, we can share their information and their knowledge, we can also laugh with them about moments they really never forget it and it happened once upon a time. All of this some governments -like China- Deny it and want to block youtube and other websites we can get knowledge from it.
