Many of Adobe's products are mature and fully featured for a lot of professionals. They don't need new features. Adobe has been nailing things on top of PDF and Acrobat for several versions.
The vast majority of work can be done with much older versions of Photoshop --lots of the new features mostly amount to saving time or needing a little less skill to be input.
(OK, time is money, and there are some genuine feature gaps in some of their software.)
But instead of fixing long-standing bugs, which would attract old customers, they're going for the shiny unnecessary features.
Take a look at the Adobe CC forums, and you'll see thousands of complaints -- advertised features in CC still not implemented; Cloud outages and deleted files; problems with authorisation, downloading and over-charging. There's even a massive thread discussing alternative professional programs.
If you're just using Photoshop, then maybe you can get Preview to open up your .psd files if you stop subscribing. (Good luck with any really heavy file, though.)
Try that with InDesign files. The lock-in is real.
Adobe's rental model is nothing more than a protection racket. "Those are some lovely files you've got there. Be a shame if something happened to them."
Yes, as a professional, I earn more than $30 a month. But CC is not my only cost. I have fat years and lean years: on the rental model, my basic running costs have permanently increased, rather than me deciding to treat myself to an upgrade when I have the cash (or even credit) set aside for that.
Adobe now has no incentive to provide all the bug fixes it claims users are now paying for.
The other myth is that I get all the apps for a cheaper price than the Master Suite. How many people use ALL the apps? How many video editors use InDesign? How many printers use Flash? The whole thing is a false economy.
People ARE running away from Adobe, screaming. This "deal" is evidence that the CC model isn't working.
