The parent post demonstrates many of the problems with modern IT departments.
Firstly, note the unnecessary and repetitive use of derogatory terms for customers and general profanity. Hardly professional.
Second, complaints that the users are undermining IT perfect systems by buying devices or installing software. Basic economics tells us that users are investing money and time in these thing because they deliver value. Value that It is not delivering to a demand from their user base.
Thirdly, complaints about having to troubleshoot problems. Isn't that what the business pays you for? In the case of a downed DSL service, a competent network engineer could diagnose that in minutes. I'm sorry it took you three weeks, but transferring your aggression to others is not productive.
Fourthly, assuming that when users ask for something new that they must be dumb. Why should my phone and PC use the same email password? Basic key separation suggests distinct keys are superior. Note also, that a phone is not a PC. It may be difficult or impossible to respond to a mandated password change from a phone using systems that assume a PC interface, so usability is served by having different mechanisms and perhaps different password change policies. Now, I understand that the software you are currently using may not be sophisticated enough to meet evolving user demands. But that is not a user issue.
Fifth, the wireless access point anecdote highlights appalling sysadmin practices. One point of access into the network and the bad guy was able to destroy critical infrastructure. Way to put all your eggs in one basket. The sysadmin of that network was incompetent, negligent, or both. Yes, the user did something stupid. But the real fool was the the person who did not design for defense in depth.
It seems that many IT departments see themselves as a law unto themselves, dictating to users what they can and can't do. We've seen this cycle before. It was last at its peak during the mainframe/mini era, and those IT cathedrals were obsoleted by the PC. My advice? Pay attention to your customers and give them what they want. That way, you'll always have great job prospects.
