I will join the others in pointing out some of its bullshit. I did not fully read it, this caught my eye:
If you’re a part of the core “design” team of GIMP, the first thing you could do is getting rid of that logo.
My point being, an Otocyon holding a paintbrush simply cannot go up against a seven-hundred-dollars-a-piece software.
http://en.wikipedia.org/wiki/GIMP#Mascot vs (I guess) http://en.wikipedia.org/wiki/File:Adobe_Photoshop_CS6_icon.s... ? The PS logo looks like it was made by a undergrad amateur! </snark>
Also I do not see GIMP in any need to "go up against" commercial competitors. It is a nice and complex program. I use it for years and I like it. Photoshop confuses me to no end and I am incapable of the smallest tasks without asking or reading guides. There are also great alternatives to GIMP which many people seem to ignore. It seems trendy to hit on GIMP without knowing better. I suggest checking out Krita, MyPaint, RawTherapee, Darktable, GIMP Paint Studio for alternatives depending on the use case.
