I have to work with ISO-purchased pdf documents that are heavily DRM-controlled. I can only open them on two PCs with a plugin that only works in Acrobat reader. It is so closed and unusable.
Just today for the purposes of ending my blog post in a good light I created the Software category in the directory, to list every alternative I found interesting to Adobe's offerings.
Here the direct link to it! https://martyr.shop/directory/#software
Personally, I use Affinity, Resolve, Darktable, Blender, and Figma. This pretty much covers any visual creative endeavor I have, very comfortably. As a side project, I'm creating patches for Wine to make Affinity work much better under Linux, because Microsoft is also smelling much like Adobe :)
