Because I have exactly zero interest in deviating from what I should be focusing on (my business, my product, my clients, my revenue stream) to go dork around with a text&#x2F;code editor.<p>Doing so, in the context of a real working business with clients, projects, timelines, deadlines and deliverables would be irresponsible if you can simply pay a company for which that product IS their product and business to deliver what you need and support it.<p>I can see messing around with FOSS as a hobby but unless you are a huge company that can afford to lose clock cycles to your devs playing with FOSS or a medium size company for whom FOSS is a a business it just doesn&#x27;t make sense.<p>The vast majority of software developers across all disciplines (there&#x27;s a huge world outside of Silicon Valley, Web Dev and Mobile) have exactly zero need or interest in deviating from their mission to go fix their tools.<p>This is the same reason the vast majority of software developers (again, think outside web folk) have exactly zero interest in vim.  It is an utter waste of time compared to point-click-go-go-go.
