Slashdot has gone downhill, yes, but so have the GTK+/GNOME projects. They HAVE been removing features and APIs without deprecation in minor versions, and are hostile to contributions/patches (case in point: why did you need to pull working patches from Bugzilla? why haven't they been merged already?).

The easiest thing to do is just say that Slahdot is a bunch of haters (it is), but that's ignoring the huge PR problem the GTK+/GNOME projects have—one they refuse to acknowledge or do anything about.
