You are right. One can use GIMP or Inkscape to design visual interfaces. But the tools on this list are nicer.
sketch/illustrator/photoshop are not “nicer” than figma/affinity designer/affinity photo. and also im being intentionally prickly because this is a low effort listicle, basically an ad for the company you work for, and was clearly gamed with fake upvotes.
We do like to share our knowledge. It's a way of giving back, and I'm sure sharing our the experience is useful to a lot of people out there.
I highly encourage you to take a look at what we have shared re design. I guarantee you it is not low effort at all: https://www.imaginarycloud.com/blog/tag/design/
This particular article might seem simple and easy to write, but I guarantee you it was not.
These tools on the list are the tools that we use everyday. So for us, sketch/illustrator/photoshop are nicer than the other tools. As a disclaimer, we try other tools (Figma, Framer X, etc) whenever a new tool comes out or suffers updates to see if it improves our way of doing things.
Sharing simple and fluid ideas is not easy. If you don't share your thoughts regularly, give it a try. After some time things will get smoother, but still far from a walk in the park.
Regarding the upvotes, as a respect for the authors, we do share the articles in several places that we find the audience might find them useful. We sometimes share the link not to the article, but to some forums where the article was shared instead.
