"Software as a Service is impossible to pirate and generates continuous income rather than a single upfront fee. That’s all you really need to know to understand why there is less and less desktop software coming to the market these days."

The other reason is platform control: there's continuous tension between the desire of each OS vendor to differentiate their platform and make applications part of the desktop experience, and the desire of application vendors to be able to deliver to any customer using the minimum number of platforms.

SaaS vendors will build mobile apps (1-2 platforms), and desktop applications in Electron (kind-of 1 platform) as service clients, but I agree that they are not incentivized to build local-first applications.
