Eh, this one's a little tough. Both my wife and I extensively use Photoshop, Illustrator, and InDesign on a frequent basis, and we're not even designers, we just like to make stuff. I've tried alternatives like Gimp and Inkscape, but they really don't even come close. I've never found an alternative to InDesign at all. There are some applications (especially photo editing apps on Mac) that are nice, but still don't really give you everything the CS suite gives.

Do I hate that I used to pay a (large) one time fee for a version and now I've given them thousands of dollars more than I'd have preferred? Yes. Do I think this 12-month contract dark pattern is scummy? Yes. But I also can't find suitable alternatives either, so in a sense they've earned their money in that regard.
