    Trying to assess the performance of the engineering team with the money the
    company generated
 

But is that wrong? And if so, why? We're hired, as engineers, so that the business can make money. Insofar as our excellent engineering makes the business money, it is valuable. When David Hennemeier Hanson wrote the Rails framework for Ruby, his justification for using it was not that it was more elegant than Java, although it certainly was. It was that his convention over configuration approach allowed small teams of developers to launch websites quickly, by having the framework assume that they were doing things in "sensible" ways.

    would lead you to use let's say crappy php web framework
    everywhere

Maybe we should use more "boring" technology like PHP and Java. Has the continued replacement of Java with PHP, PHP with Rails, Rails with Node.js actually benefited our customers? Or has it benefited programmers' desire for novelty at the expense of our customers? At work, one of my co-workers proposed writing a new front-end component in Vue.js, rather than React, because React was "old" and "showing its limitations". I pushed back, arguing that all the rest of our code was in React, and I wasn't sure that he'd necessarily made the case for Vue providing tangible improvements in maintainability or speed of development. We went back and forth, but in the end he won out, and now we have a bit of Vue in our codebase. Has this improved anything for anyone, other than the programmer who now gets to say on his resume that he's implemented production code in Vue.js?

EDIT: That's not to say that I'm against all innovation. There are certain classes of innovation that have definitely brought tangible improvements in the speed of development and reliability of the software developed. Memory management is a big one. Going from (legacy) C++ to Java is a huge step forward, just by freeing the programmer from having to worry about the most common sources of memory leaks. Likewise, strong type systems are another advance, that is just coming into the mainstream with Rust (and, to a lesser extent, Typescript). Lisp-like languages (although little used) offer another step forward in productivity by allowing the programmer to write functions that can inspect the internals of other functions as data.

But I feel like that's a different category of thing than trying to argue the merits of React versus Vue or Python versus Javascript.
