Just curious
How are you going to maintain access to all your files once you cancel your Creative Cloud subscription?
If she's canceling her subscription, then she's probably not too concerned about it. So long as she saves out her images in a standard file format, she can keep the .psds and whatnot hanging around until she needs them again, which she can open up by resubbing.
...or by making a fake account with a fake email and riding the 30 day trial.
I don't 'occasionally dabble'. I make a living using Adobe software, and have tended to upgrade quite regularly over the years. But I refuse to go down this path. I think Yoda said it best
'Once you start down the dark path, forever will it dominate your destiny. Consume you it will!'
Like I said earlier, I'm not totally sold on the whole idea of subscription software myself, but I do see some pluses alongside the cons. While it's not all kittens and rainbows, it's not all gloomdark wastelands and bloody mangled corpses, either.
There are advantages, such as having an ever updating, constantly patched version of Photoshop for the price of one good pizza a month. The downside being, yeah, you cancel your subscription, you can't open your files. But you don't lose them. You're always another sub (or cheat) away from being able to open them again.
Personally, I'd rather buy my software. But I'm not 100% opposed to the idea of subscription software. If I find there are more upsides than down, I'd be willing to take the plunge.
