These are all examples of pretty amateur mistakes. This reads more like an argument for keeping senior devs on the payroll than a warning about not using a framework.
A framework will not prevent things to become a mess, in the angular project I inherited in most places the rootScope is injected everywhere, I do not blame the developers either, the angular architecture is not great and when you have a lopt of new tasks for you to implement you don't always have the time to reimplement things, but sometimes the correct solution is not used , though you may want to claim that your favorite framework makes it harder to do the wrong thing.
