You should know that in the past when OOP was not common, we had to work a little harder doing things like managing our own memory or building a LAMP server to publish our web pages.
There was a thriving market for language and UI add ons. The result was that each company had their own internal dev tools and recruiting people outside of the company who had experience with those tools was nearly impossible.
All that said, we were at a point where entry to programming was easy (think Visual Basic in the 90s). The quality generally went down as everyone was pushing their "first project" as if it was a polished product. Finding actual good programs on PC is close to the situation on mobile where most of the apps are trash.
