I must be doing something wrong, because all of my work over the past decade was done using mostly (like 95%) free software. And as a hiring manager I cared not at all if my hires know about "enterprise commercial software". In fact, I'd also add that the time I spent learning commercial dev tools (Microsoft stack) turned out to be absolutely useless in the long term. Worse than useless, in fact, because I could have spent that time learning tools and libraries on which some commercial company doesn't pull the rug from underneath me every 2-3 years, like Microsoft has a habit to do, to force upgrades.
