To put it simply, this reflects an amateur understanding of frameworks. I know where the author is coming from, because I've been there/done that/tried that. It sounds nice on paper, but experience has shown that this is a poor way to approach software development.

I see this kind of mindset with developers who think only about code, and not about solving problems at scale with other people.

Totally agree. Hiring is the big one for me.

As a business owner, you need to be able to easily find new developers to slot into your team who can get up to speed quickly.

This is much more easily done when your app is something like Rails, Django or Laravel.

Don't you want the engineers who are language agnostic, and have seen many a many framework and can quickly learn any quirks from your existing team?
