I have to say there are SaaS solututions that work just fine to be priced per seat. For example JIRA where it is part of job of each person to handle tickets/tasks and they have to have separate accounts. There is also basically no feasible way to abuse JIRA unless one does not care about who did what and when so throwing tracability/accountability out of the window. For solutions like Adobe Photoshop as an example, I would not care who used it in our company, I just care about the result. Managing licenses for it is just annoying burden and I can see how people would like to have one account and pay for usage. It is also quite easy to abuse because output is not tied to person work as in accountability/who changed what/ way. I would say one has to understand his product and how it is used instead of "never do X" advices.
