The pendulum is definitely ready to swing back the other way. A related problem with SaaS is the risk associated with whether or not the company will endure (and open-source-on-company-failure is not confidence building imo).

https://machinebox.io/#pricing is one example that I like of a product that goes back to software-as-a-product. I've not dug into the operational aspects of this product, but if done well should be able to scale from a dev's laptop to k8s or other PaaS.
