There is legitimate reasonable criticism of these things, even today.
However, they have also been subject to profoundly unreasonable – even unhinged – criticism, and this has created a rather unhealthy dynamic where both reasonable and unreasonable criticism are all treated the same by the developers. You kind of need to insulate yourself to some degree.
For example, consider my write-up of the "GTK thumbnail issue" at [1] (I since deleted my account there, but that was written by me). It's easy to come off with a bad impression of the Gnome/GTK developers based on that, but at the same time ... they've been subject to so much unreasonable whining and criticism that it has also created this dynamic.
There's tons of examples like this. Also see: every time GIMP comes up on HN, with people ranting and whining about all sorts of things. I wouldn't be surprised if the GIMP devs don't even bother reading HN any more.
