The reason is simple - nothing really bad has happened that we can point at and say "ah, shit, let's all learn collectively". I know it sounds naive when I say it, but there hasn't been a significantly consequential hack, leak, destruction, or anything related to cybersecurity where it led for concerns of people.

The main thing I can think of is cyber insurance, which requires a bunch of audits, and some checks maybe, and it changes some conditions whenever there's a big explosion. Whenever big leaks happened, data security and etc., nobody really went to jail, so nobody really cares. Everything can be brushed off, because it costs time to implement proper measures and adds friction / barriers in some cases. So in the end, there's a huge pushback against it. And I totally get it, to be honest.
