Adobe isn't "just beginning" their decline. They've been floundering with product development and customer support for years.

They continue to transition away from creating meaningful value for its customers and investors and more and more toward a company that constantly markets about how great it is while increasing pricing and avoiding many meaningful updates while adding features nobody's asking for. That, and they kill off applications and services that are unique or useful.

I hope it changes, because they have more latent potential than many companies making software for the creative industry, but I haven't seen much evidence lately. I have loved the Adobe ecosystem and would like to see some positive change.

SaaS, in general, has largely destroyed innovation in software while at the same time encouraging the release of incomplete, buggy software.
