Earlier quoted context omitted.
The "entitlement" is from people who are frustrated that the open source software movement lacks such a fundamental piece of the desktop software puzzle. The confrontation comes from the fact that one side insists the software is there (GIMP), whereas the other side view them as disconnected from reality since its use in industry rounds to 0%.
I don't see why perceived usage share in industry should motivate dissing open source devs. GIMP has a user base and fans who obviously think it's good enough for their needs. If the professionals in the industry and their employers have a need for an all-in-one free software that can do everything - image editing, illustrations, maybe throw in 3D and animations while we are at it - then the industry should contribut…
And I think the attitude comes in when GIMP is ignorantly held up as if it were a serious competitor. It isn't. It's something else entirely. It might be good enough for people to make memes for internet shitposting, but between the missing features and the alien UI (to the point where a massive reskin [1] was around for a while), it's never going to be used in industry.
If the GIMP devs want to continue down this path, more power to 'em, I just want the people claiming that it's a Photoshop competitor to educate themselves :)
