Security is always the very last thing they care about, until there's a huge very costly breach. Then they care for 2 months, and I get to actually work on the security stuff, and get other developers to cooperate, and clean up the known messes left all over in the typical mad dash of feature addition and replacement. Then it's all forgotten about again.
They should say "we suck, we focused 100% on features and market share, we know now what's important", and they should get security right. It does kinda suck that the market often rewards companies that prioritize all else above security, and I wish such companies all the damage a breach can cause. Otherwise, there's no reason to not suck at security.
They should just be honest: "This is what happens when you make a product people love. It's insecure and data is lost and service is interrupted. But you all love it so thanks :)". People should not be under the illusion that their favored products and services are secure. They should know they love insecure shit.
What most people don't realise when it comes to computer security is, the foundation on which our modern systems are built never anticipated this much growth.
I think I am happy with companies that care enough to come forward and admit their mistakes. IT security is hard, very very hard.
You really need a good security guy who can be the bad guy and stop projects in their tracks when it's clear there are security issues. Because asking the same people who are accountable for shipping to stop the presses to fix even the obvious shit you already know about is a challenge - much less investing resources in 'shoring up' against attacks you don't anticipate.
If there are people that truly do care, they should stand up in the early process and make sure enough budget is allocated.
