Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
I think it means convincing people to drop the proprietary platform and telling the sales rep that both lack of Linux support is why you’re dropping them and what application you’re switching to. As long as you’re still a revenue stream for them they’re not incentivized to change. I do recognize, though, that this isn’t always professionally possible as the end user.
