To me the 365 subscription method is just an irritation I can live with. But the price increase is another matter. There will have to be something really significant for me to afford that. We shall see.
As a long-term user I tend to have created my own content, cannibalising it if I need something new, rather than downloading from the Xara galleries.
As for Adobe, I find their abandonment of CS, now no longer supported, a great incentive to remain with Xara.
