I think that in a part it's an effort by big firms to industrialize certain aspects of software development.
Take for instance Oracle using java to sell their services. They also needed a mass of easily trained, relatively cheap programmers that would support this business model. And this in turn put constraints on the language, and tied it to its tooling, because the tool assisted java dev was part of the Oracle business model.
It was so successful that G0 0g le was able to use this very same cheap pool of programming labor for its mobile application ecosystem.

Same thing nowadays with javascript and R*st.
You have all those firms selling "Cloud" solutions and there has to be a pretty big number of relatively cheap devs, completely dependent on proprietary libraries and infrastructure, implementing said solutions for end clients.
The modern javascript WebDev is a crucial part of the modern online monetization scheme.

Their dream scenario is the equivalent of going from needing mechanical engineers to employing machine tool operators working in a mass production line.
