These are good points, but I disagree somewhat about the ops burden issue of SaaS. The ops burden issue is due to problems that are all solvable, and if people paid for software there would be a strong incentive to solve them. Instead we've revived the technicians in white coats tending a mainframe model because that turns out to be what people will pay for, and I think this is mostly because the model doesn't give them other options. Edit: also while there is a marketing distinction between B2C and B2B ultimately everything is B2C. B2B is just B2C at least one level removed.
