I am not sure we are making different points, just emphasizing different parts. I agree with the point that frameworks exist to have opinionated solutions for how to do things, whatever those things are. If your opinions differ you need to understand how you can tweak, bend, and modify the framework to let you enforce your opinions. If you can’t then you need to examine what your organization does. If your org is…you then do whatever you want. If your org is bigger than you, changing frameworks May not be feasible.

The original question was about whether learning frameworks is good. I think the answer as you say is that it depends what you’re trying to solve, but you can get a lot farther and accomplish a lot more to a point learning frameworks than learning how to build a framework’s components yourself.
