being the keeper of the "company firewall" at my company, the reason so much is blocked is that users could give 2 shits about what sites they go to and if they infect their company owned PC. Which, once it gets infected because of said web surfing, the user bitches and moans that the machine is slow and at how long it's taking to clean it up.
and THAT gentlemen, is why we bad ol' IT guys block so much with a firewall.
carry on
