There's more proof from someone with skin still in this than not. I think you will find it hard to get anyone to believe one's word about this company if they say they have no shares but remain here just to tell everyone how much this company stinks. It sounds "fishy" as you put it awhile back.
Maybe it is crap here, maybe it's not. But it is even better to push a stock to get out as good as possible rather than to talk all bad! If he is in no interest here, he should go his way and be quiet!
