I am an assistant professor. If you came to my office and told me to use anything, I'd kick your IT-fiddle-monkey-ass to the door.
That's because you have little respect for others based on the tirade you just posted.
Here's something I really want university IT guys to get through their thick skulls:
You work for us. Not the other way around.
I'm not sure what it is that you teach, you didn't mention that; however something you may need to get through your thick skull is that professors, doctors, lawyers, and other professionals are good at their profession. They suck as any authority for IT work. They need to stop acting as if they have any experience dealing with IT whatsoever. I don't tell you how to teach your class, don't tell me or him how to run my network or his workstations
If I want to use a Windows machine, you need to figure out how to let me. If I want to use a Mac (which I do), you need to make sure I can get to my servers. If I want to use Linux (which I hope to be doing one day--when the software I need to do my research is available on the platform), I expect your support there, too.
No, you run what the university deems as the most cost effective, safest software they can use. Your needs are of a lower priority than the security, safety and reliability of the University's IT department. They are entrusted with that, not you. They entrust you to provide knowledge and experience to students; stick to that.
In the specific case of what you're proposing--moving to OSS for all everyday tasks, I have to be totally clear and honest here: You are wholly unqualified to make that call. It's not your job; it's not your responsibility; it's none of your damned business. You don't even know what I do; how could you know what I need?
That may be true. He may be unqualified to make the final call. But IT's is responsible for your network stability, security, and support. It should be their call as to how to handle this, as university professors do not know enough about computer networks and systems to be qualified either. You're a rarity in a bunch of academics that have no more training than the average office worker.
Finally, let me say this: My first jobs in academia were in IT support, and I, too, got drunk on the power. I, too, was young and full of myself, and I, too, ran around telling people what they should do, instead of listening to what it is that they needed to do, and helping them do it. Now that I'm on the other side (and older and less full of myself), I see why I pissed people off so much in those days. I sucked at my job.
If you try to meddle in your customers' business, you suck at your job, too.
You seem to forget that yours and others workflow is based upon a device given to you for your use by the university. These are their tools; not yours. Your workflow needs to conform to their standards of operation for IT, not how you would run things.
It is unprofessional to suggest that you, an academic, should be the deciding factor in how IT infrastructure is run. Again this is like me coming into your classroom and telling you how to run your class; I wouldn't do it, so where's your justification for why you see fit to tell IT how to do their job?
How you choose to run your computers and/or networks at home is your business, but at a business or at a university, you run your system the way the business or university designates it, and if IT designates that you run using certain products, then you'll run them that way. If you were running on my network, you run what I say you can run, end of story.
