He's not. It's a really big issue. People (read sys admins) have lost their jobs more than once for installing DC projects on systems they controlled but didn't have written permission from the actual owners of the machines. In the US you can actually be charged (not sure what states, sorry) for theft of company resources if you use company computers to work on your own projects, DC work (like WCG, F@H etc) included, without the right permissions.
