I am far from shitting on GIMP. But truth to be told, it's not very pleasant user experience. And I feel like there are several fairly affordable and significantly better commercial alternatives to Photoshop.
and
to name but two.
The Gimp is dire software and needs taking out and shooting. It's one of those awful apps that people who know nothing about digital design always trot out whenever others bemoan the lack of Photoshop on Linux. A recommendation that does more harm than good, as anyone who's used Photoshop and gives The Gimp a spin will end up thinking "If that's the best Linux has to offer, Linux must be rubbish!"
Ever since they started offering the Windows version as well I've been using Affinity Photon exclusively. I'm not doing a whole lot of photo editing, but when I do, I don't want to bother with the awful user experience that GIMP provides. I'll gladly pay 50€ for a software like Affinity Photo that offers almost the same features as PS while also being able to work with a lot of Photoshop file formats
Spend another hundred or so on an Apple pencil and some font licenses and you are flying.
FOSS is a free market. The mere fact that GIMP isn't meeting users' needs is supposed to result in competing, superior forks driving it out of business, not a desire to give more money to the incumbent.
