Here's my perspective on it: if you can't understand that this is pre-release software and it's going to be riddled with bugs, errors, and generally odd design decisions (that generally aren't design decisions at all, but rather incomplete progress) and respond maturely to that, what you need to do is
UNINSTALL.
You are not contributing by whining. No, it's not the same as giving feedback. Feedback is useful if it's delivered with a mature tone and reasoned analysis. No, you don't have every right to complain. It's not a release, we're supposed to be looking for problems, and if you get upset every time you find one, your feedback will probably be filled with hyperbole and ultimately without value. Please stop clogging up the thread with it.
