Yes and use what? It's not like there's a serious option that's an industry standard. I've never worked in a game studio where artists used something else beside photoshop or someone would even consider something else. They have the same kind of lock in microsoft had, it's not just about the "os" it's about the giant ecosystem of plugin built around photoshop, the millions of line written in custom import script for art assets in most studios, etc.
Also, the thing that strikes me the most is that everyone seems to completely misunderstand the impact of the cloud service being down. They way Creative Cloud works right now is *the same* as Steam works, you use it to download and manage your software. You software is not running in the cloud, it's just a fancy pant download manager. The impact is NOTHING for users who have it installed. The only thing that's impacted is users who want to download photoshop or whatever. They do warn you: "Oh btw, you're not connected to cloud service, make sure to reconnect before the END OF AUGUST if you don't want your software to be disabled.
My users don't really care if their software is being installed through "Steam/Creative Cloud". As a matter of fact they are not allowed to mess with that anyway :). The real story is more how the licensing deals are changing, that's all. For the current studio I'm working at, we've found that *currently* the CC deal is way cheaper and anyway other options are going to disapear. It's not like we're stupid and we don't see what they're doing by trying trap us all with CC licences and THEN jack up the prices but there's not really any choice. Frankly they'd have to jack up prices to some pretty insane level before we'd have to call it quit, too much legacy software is riding on this.
