I linked you the github page with the issue. There you can see the video of the printer destroying the flow stopper by moving in a way that got introduced in the beta and should not happen.
And here is a forum post about it H2D beschädigt sich selbst? - #10 by 2B.MainPrints
Why do you think they immediately removed the firmware from the public again? Pushing that to all H2D owners would result in way more broken parts then just the few beta testers.
I never exaggerated, its you writing in caps and acting all weird.
