>> I think about this often. I feel justified by working on a product that is strictly B2B, enterprise software. No predatory practices towards end users. Is that any better or am I deluding myself?

I think the question is whether you're providing an actual service that has value, or just charging rent for the software and calling it SaaS. Software has a marginal cost of ZERO, so SaaS is often simple rent-seeking. A company might actually use the money to develop a better version of the software, but that's actually optional on their part.
