> For example when is the last time my customers paid for Ruby, Python, Linux, PostgreSQL? Well, those examples are cherry-picked; ergo, I present to you a picking my own cherries: Companies pay for MATLAB, Windows and MongoDB. I will concede this list not "very long". But length of lists shouldn't really matter here right? I mean, one example of MATLAB vs. Ruby/Python is good enough to make a point via counterexample. The point I'm making is: It would be immensely unfair to expect developers to force MATLAB engineers to submit to whatever business model the devs want instead of the other way around. Companies that develop technologies own the right to price it however they please. Competition in the free-market ensures companies do not employ price-gouging tactics.
