When Creative Cloud came out, I thought is was a great idea. While primarily a Lightroom, Photoshop, and Acrobat user, the $30/mo (later to be $50) gave me a chance to try out, learn, and occasionally use some of the other products. So, even though I had licenses for LR4, PS-CS6, And Acrobat-9, I signed up.
The removal of the ability to get an "enduring" licenses has caused me to reconsider that....and prepare an Adobe exit strategy.
I have uninstalled Acrobat XI, and reinstalled Acrobat 9...and it is probably all I will ever need.
At the end f my current CC term, I may get a single CC license for PS-CC. While annoying that I could lose the "work product" without an enduring license of the future PS-CC versions, I could survive with the (non-proprietary) RAW files and the TIFFs.
The day Lightroom is no longer offered with an enduring license I will plan my total exit from Adobe.
This will be difficult as I really like the product. However, I cannot be reliant on a product that could be gone in an instant....and only leave me with the unprocessed RAWs, with no availability of my develop or organizational effort.
