Just no. Our IT department is 100% Windows focused. I can't get help to anything that isn't "a Windows problem". I can't get ports open in the network, I can't get simple things like mosh to work, because again it is not "a Windows problem", so I am not going to let them screw my perfectly fine machine with some Windows bloat ware there is a reason why no one is dev is running Windows.

Worker cost 50 money. How company get 50 money? Worker not work so much, maybe? How to quantify? What if spy? Company tell IT monkey to give developer monkey spy. Our computer, company can do a little spy. Company catch smoke break. Company catch walk break. Company give worker "performance improvement plan." Company fire worker. Company now have 100 money. Company smart. Company efficient. Company legally protected from retaliation. Company give executive monkey 30 money as reward for small overhead. Company offer manager monkey 7 money. Company offer IT monkey 3 money. Company brag about in annual report.
