Right, and mine likes productivity. I'm sure the business that's expending resources to try and circumvent my firewalls has a firewall and a usage policy that their employees adhere too also.
So if you circumvent my original blocks, as an administrator, I will use my home-field advantage to just start targeting your individual users and remote resources. Suddenly your users can't even get on Google. Then they'll have to come to me for "the talk."
So the decision quickly becomes a) circumvent enough firewalls that you blacklist yourself or b) get all your users blacklisted for using your service.
You're assuming those blocks are there for a reason. But blocking PUT makes no sense. Getting blacklisted here requires a very special mix of incompetence and pettiness that is thankfully rare.
