What might exist though, are simpler applications for the amateur market where Adobe moves purely to the professional market.
I think the software market is more complicated than that today. For example, a lot of people have been using Photoshop and Illustrator (and Fireworks) in recent years to design graphics for web sites and user interfaces: icons, logos, background images, that kind of thing. However, there are several applications available right now on OS X that are not only much cheaper than Creative Cloud but also get much more positive comments from professionals who are doing that kind of work.
Basically, we've all been trying to force Adobe's 800lb gorillas to do the job for years, but the reality is that we were just waiting for someone to come along with a tool aimed at exactly what we need to do, with a feature set and user interface tailor made for that kind of work. Now several different businesses have, and if the people in the industry I know are at all representative, those newcomers are already attracting a significant share of the professional market. Not only are they cheaper by far than Photoshop, they are also significantly better in that particular niche.
This is why I suspect it's a matter of time before Adobe's behemoths start to suffer a serious exodus. Rather like Microsoft with Office, they are trying to be all things to all people, but that creates huge application suites that are inevitably full of compromises and expensive to maintain. It's not LibreOffice that Microsoft should fear, it's tools like Scrivener stealing all the professional authors, some modern replacement for TeX stealing all the technical people, on-line collaborative editors Google Docs stealing all the casual business users, and so on. It's death by a thousand cuts.
The thing is, getting back to where we came in, the requirements for an operating system are quite different. If you're writing the foundation that all of these other applications are going to run on, then stability and longevity are vital attributes. So while I think Adobe's move to a subscription model will probably be successful in the short term but in the longer term it will prompt more effective competition than they've faced in ages, I think Microsoft have a natural ally in offering long-term support at a price because there are always going to be updates people want for compatibility with new hardware and software without sacrificing compatibility with what they already use.
