I don't think that's the argument. Direct Linux support is going to be very unlikely anywhere, but using open standards should be common in universities and the difference is between "do you support" and "is it possible to use".
As for the whole "noone allows linux on their work desktops", people used to say this about macs too (outside design), now almost 1/2 of my office uses them. Not just coders/designers either.
