As someone who's worked in IT, in corporate and not so corporate companies, it's often not that the support techs don't care. It's that management doesn't. In most companies, I was explicitly told to not care about certain things. If I cared too much and spent too much time on one single problem, to fix it for good, I was told off. As long as users could work in some way, it didn't matter. Even if that included ineffective or costly workarounds. That kind of thinking has and will always rub me the wrong way.
