Graphics professionals working on Linux… are as rare as mermaids?
There are lots of good alternatives to the Adobe products that cost a little money. Anything that takes 4 years to fix 700 bugs is not being used by professionals.
I'm not a fan of Adobe and happily use alternative products (Photoline is pretty good) but the new pricing model actually makes it easier to pick up casual business. Some professionals will no doubt (rightly) complain about being fleeced by the new model but it does allow for faster release cycles. As soon as it costs more money to use the stuff than you get make from using it you should cancel the subscription.
