Hardly a fair comment.
As Mini has pointed out, someone who has sold out of NZO or any company but has good insight (and good infor) makes an even better contribution by highlighting the inadequacies of a company. It is up to the company to refute the assertions or to accept them.
I have no grudge against NZO but I find good assets (especially cash from shareholders) being grossly mismanaged extremely aggravating.
Pray explain how a company like NZO siting on a pile of cash end up re-investing in PPP (sell low, buy high) and pouring in endlessly into PRC?
