I'm not IT bitch

Everything in that post seems valid but when it's coming from an entrepreneur, copping this attitude seems self-defeating. That person who just mistakenly or ignorantly referred to you as desktop support could be someone that could help you in the end.

Please take this as just frankly worded feedback: It's quite possible you think more highly of yourself (or your work) than you really should. You say you agree with Linus Torvalds quote, but chances are you are not at his level (yet) to have earned the right to get so snotty.

Wait until your firm is overrun by adherents of the Information Technology Indoctrination Library. Managers will become smug, platitudinous mansplainers (self-styled experts on matters of common knowledge) who believe that everything is IT, even programming, which they think they don't need to know anything about--for them, soft skills rule. And their intellectual apparatus cannot resolve the difference between computer science and IT--brief exposure to ITIL depresses cognitive ability in every measurable level, out of proportion to exposure. If you're not part of the ITIL "service as a service" process, you're part of the problem in their view. Never mind that foisting the mind-numbingly boring ITIL corpus on employees forces the better ones out. You'll be required to sit in on Bolshevist change management meetings with everyone else in IT.
