Yeah I'm aware, but as any company gets larger and has more and more traffic (and money) dependent on their existing systems working, keeping those systems working becomes more and more important.

There's lots of things worth protecting to ensure that people keep using your product that fall short of "lives are at stake". Of course it's a spectrum but lots of large enterprises that aren't saving lives but still care a lot about making sure their software keeps running.
