To be as polite as possible without being dishonest; wow, there are a few rather sweeping, unsubstantiated, boiling hot takes embedded throughout there, i've just quoted one.
From my experience, most of what features here just simply isn't true, or is at least very anecdotal. Just as one example, i've never worked for any software company that "wasn't about the users". You really do just only need to look at how much "UX Specialist" roles have meteorically exploded over the last ~decade or so, as companies compete to offer increasingly smoother user experiences, and it is hammered into the actual developers too as a core operating principle everywhere i've worked.
