As a front end developer with nearly 20 years of experience I can objectively call bullshit.

The problem is Invented Here syndrome and coddling. https://en.m.wikipedia.org/wiki/Invented_here

The reason this exists is due to a lack of leadership in the front end space. More specifically, a need to hire untrained entry level developers and deliberately not train them whether due to insecurity elsewhere and a complete inability to write documentation.
