I instinctively dislike when a product that I have bought at a fixed price becomes a utility, something (like electricity and water) that I will never stop paying for, etc.
In Adobe’s case, despite all the online weeping and gnashing of teeth by users, for me it has been a blessing and probably cheaper. I use most of the Adobe products, and so I was maintaining the Master Edition (or whatever they call it), which was very expensive to initially buy and had expensive upgrades every couple of years.
I need the way the various Adobe products are threaded together so that I can seamlessly switch back and forth from one product to another. Especially with Photoshop and Premiere Pro, I need to slip in and out of these at will. And, as you mention, I like the idea of adding new features as they are ready, rather than wait until the spring of the following year or even later.
I find Adobe Creative Cloud easy to use, easy to update, and it tells me clearly what I have updated and what I can update, and what’s included in the update. I feel that Adobe made the switch at the right time, and it was the right thing to do… for me, and not just for them.
