If you don't see it, it isn't there.
Maybe they hope that, if they don't acknowledge the presence of the specific error message, it makes the problem simpler, somehow...
Or else they're just too damn lazy to do anything about it. I lay even odds on the two alternatives.
Incidentally, if you decided to be evil and require the error message before you fix anything, you might see a change in this trend. I know that, for instance, the ALSA support list does this.
