Retraining people to use new tools on a corporate scale is an immense endeavour, probably a huge cost given the dip in productivity, and that's assuming there is an equivalent Linux tool in the first place.

For some people, learning new stuff isn't as easy, and they just don't have the investment to do so when all they want is to go about their day. The expectation that people shouldn't be so reluctant to learn something new ignores the inflexibility that long-established habits bring in some demographics.

Conversely, while that demographic is locked into using Windows by virtue of the cost-benefit function to learning something new just too... not be using Windows anymore? is just unfavourable, others will have to cater to them.

Technology is advancing way faster these days, and it's unfair to demand that everyone keep up with it. Hence, while recommending Linux is a good thing, being an elitist about it (as the people my previous commend alluded to tend to be) is unproductive.
