When all my experience with image manipulation programs was paint.net and I wanted something more powerful I tried gimp. I hated it. I saw it was powerful but the ux just isn’t great. It’s really complicated and unfriendly for new users. When I then tried using photoshop, it was really easy to get into. And that’s a general problem with foss. Most big closed source programs had millions spent on ux research. Most foss programs never think about the average user but are instead by professionals for professionals.
