I've run tor exit nodes and repo hosting when I worked for ISPs and Datacenters while at the same time shuting customers down who do the same. The difference being that I had that conversation with my boss and said, 'this will violate our normal terms of service but I would like to do this.' The boss is of course more willing to make that concession when he can walk down the hall and say, 'uh, we have extremely high usage and today, can you shut down the repos until we can get another link installed?'
