Shareholders are not necessarily behaving rationally
Innovation comes at a cost and not without risk - and will sometimes fail to pay off.
If companies get sued every time an innovation fails then there cannot be innovation, logically.
I am not at all clear if there was genuinely misleading information published, but it seems to me to be more like vultures fighting over their "share" by biting the hand that feeds them.
Being a shareholder is not SUPPOSED to be risk free. You may as well expect all kick-starter ventures to be perfect, profitable and on time.
