That's exactly my point. The markets pay for what they care about and ignore/punish what they don't. They rarely pay for security. They rarely punish insecurity. Even in security, it's usually just enough to not look incompetent when a breach or lawsuit happens. Both consumers and businesses care very little about software quality or security if assessing by what they buy, use, and stick with. You can easily prove this by giving them choices between feature- and security-focused products. Even when the latter are free/cheap and highly usable, the market still decides against them massively. The voters also don't push for regulation or liability of this stuff. Many straight-up vote against it.

So, the management at these companies operates in a market that barely cares about security or mostly cares about appearances/perception. The incentive structure rewards working against quality or security. The costs are externalized with little happening to counter that. So, the rational actors ignore quality/security as much as they can. Programmers should act no different in a system if maximizing selfish gain or minimizing work.

Personally, I'm a utilitarian that considers security a public need. I strongly favor regulations and liabilities to increase the baseline of our security. Just cover the basics like memory safety, input validation, secure admin interfaces, error handling, backups, and recovery if nothing else. The stuff we can already do today with free tools that the suppliers just don't care about. That's not what the market is, though. So, I can't blame people in it for giving it what it wants if they risk losing money or perishing focusing on idealistic goals. I do encourage those doing business with utilitarian style, though. It ranges from easy to hard work they don't even have to do. Also especially glad when I'm one of their customers. :)

Mothers used to die from doctors not washing their hands. The lack of a price signal didn't mean it wasn't a problem, it meant none of the doctors understood how to solve the problem (and neither did the patients).
