I dislike SaaS very strongly. I will not repeat the "why"s mentioned in this thread, just add one that I haven't seen yet: SaaS incentivize doing busywork that is visible but not necessarily useful.

For example JetBrain's products: Oh look, we have changed our icons/ updated UI/ improved UX/ etc! We know that nobody asked for this, but it will be shoved into your mouth anyway!

Pretty much sure you can find that everywhere.
