This is only true in certain contexts. Most of the time software quality is looked over not because it genuinely isnt important but simply because it's hard to perceive.
Ive watched many businesses appreciate the benefits of software quality (happy customers, few incidents, fast feature turnaround) without ascribing it to anything in particular.
Then, when it went away, they chalked up the problems to something else, throwing fixes at it which didnt work.
At no point in time did they accurately perceive what they had or what they lost, even at the point of bankruptcy.
Part of the problem is that the absence of bugs, incidents and delays just feels normal and part of the problem is most people are really bad at detecting second order effects and applying second order fixes. E.g. they think "another developer will fix it" or "devs just need to dedicate more time to manual QA".
Conversely, because it's so hard to see I think it can make a really good competitive moat.
