Of course I don’t mean those art-stealing cannibals over at Adobe allowing them, I mean the Wine software allowing them, as it semantically implied.
Like I said, I wouldn’t touch Adobe with a 39.5 foot pole, but Photoshop is unfortunately necessary in those relatives’ industry, so getting on a high horse and telling them to use GIMP or Krita is not going to accomplish anything.
I’ve gotten used to GIMP and used it for a lot of cool thing (especially G’MIC for getting CD liner note scans looking quite good), but it’s just not a solution for serious professional use.
