I think they mean that for the most part developers spend their time complaining instead of doing.

In the end, someone can always rewrite something that's successful to fix performance issues, but what's the point of making something performant (or focusing heavily on architecture) before you even know people want your product? Performance matters to a degree (after all, performance is a feature), but the product matters the most.

The point is professional pride and the "engineering" in software engineering.

Which can admittedly get in the way of half-assing a start-up into life... and that's why many devs are not good business men. That's a feature, assuming we don't want all our sw to be complete crap.
