Technically, I think you are right. KDE lost credibility and potential users/testers because
of this.
But I also think that there is no need for all this negativity. Everybody is bound to screw up
once in a while. While they failed in labeling the release or communicating it, they didn't
fail as developers - the technology is great (or will be) - and that's what really matters.
I think it is important for KDE users and supporters not to make a too big deal out of it.
