We have a legit PS install on my wife’s machine and it’s preventing us from making a move to another computer for her. She’s a casual/non-professional user. She knows the app and how to use it. We aren’t interested in renting the app… basically we’re holding out on that machine, but sooner or later it’s going to become a security risk in our network.
At some point it might be worth looking into Affinity Photo, it's a $55 (one-time, with free updates) cross-platform photo manipulation program with surprising feature parity with Photoshop.
This is why I still use Photoshop CS3. It's the newest version Adobe have released as an activation-free offline installer, and it does everything I need and then some.
