I don't think it's fair to say people aren't interested in it. The real problem is that software development is an immature profession. It's a Wild West, anybody can identify as a developer. There are no educational or professional hurdles to overcome before you get provide your services. No developer has gone to jail, or had their licence revoked for well-intentioned, but bad code. Incompetence is largely consequence-free, so the incentive for thoroughness is only present in the mind of the individual developer. That said, security is difficult, time consuming and expensive.
