SaaS companies are effectively both "software maintainers" and "price gouging middlemen" at the same time. The difference between the bid and the ask for SaaS is part of a simple math problem for whether the company should try to create their own version of the software they need. It may be the right decision, it may be the wrong decision, but it will be the right decision for a non-trivial number of firms. And that means SaaS businesses will both lose customers and have downward pressure on their margins. That means valuations of B2B SaaS firms go down.
