Look at it another way. Docker is a complete PITA with many severe flaws as a piece of software, but it won because it raised investor money and spent it on stuff that was then given away for free. Basically it funnelled investor money into everyone else's budgets, which is a pretty sweet deal. If they hadn't done that, and if they'd worked on scaling their business in line with revenues, then quite possibly they'd have (A) more competitors and (B) better software. But it's hard to compete with free.
