I think the difference between line of business software and companies that are actual software companies is so huge that it starts to make no sense to compare them.

I've worked on technology that goes out the door and contributes to the company's revenue stream, and I'd have been insulted if someone said I was in "IT". The cultural differences between that and truly working in the IT cost center is massive.

Most people who spend the careers working for banks and insurance companies never see the other side of the chasm.

In which case it's just one step removed. All products I have ever come across fix a pain point in one or more of the areas mentioned.
