Rant: How come some companies hate Internet-1

Sorry!!! I am no longer having access to my blog from my office. The big brother is bit paranoid and cut access to all Web sites. Well !!! that is the reason for this rant. How come some copanies hate Internet?
My company pays me to do work. They have every right to deny the Internet. While they say how "not browsing the internet" improves the company productivity, I have my own reasons to say how it helps me.
1.Internet helps me to do my work easily. For example, I copy my code from google groups half the time. Am I not saving bunch of money for my employer, since he/she need not pay for the training?
2. Can you be really secure by not connecting to the outside world? If that is the case we should all live in the islands all by ourseleves. Even the concept of family/ society have to be redefined. Ain't it?
3. Do we really save time by not allowing the internet? Well I spend time in chatting with the team mates.. my coffee breaks have become longer..
