It seems you don't understand how this model works. I have been operating with Creative Cloud for over a year now and it's nothing like you've described.
I don't want to have my UI move around arbitrarily.
Don't click the update button then... no one is forcing you to take the updates, you're just a luddite if you don't.
I don't want to work more in the cloud. I have invested a considerable amount of money in building a high performance system here, with robust storage, networking, back-ups etc. And my system and devices don't trust anyone outside my company with access to material I'm working on for clients.
I still burden my "high performance system" every day, and even expanded my system to take advantage of the new RayTracing features in After Effects with great results. The software runs locally it's just licensed in the cloud.
Oh theres another huge benefit... the license is platform agnostic. So for the artist who has Windows and Apple they don't have to get screwed by buying two completely different software packages that never stay in sync.
If you can predict anything with 100% confidence it is that you don't know as much as you think you know.
