Ex-CEO reason for leaving?

The ex-CEO was under orders to ignore the share price and focus on the device/trials.
He seemed an OK bloke; and others felt the same.
I don't think he was entirely happy with those orders.
The orders were from big holders who probably don't mind, and actually want, a low share price. With the presence of a poison pill no outsider will get control cheaply; but insiders can gain control - just drop the share very low, force a capital raising at a low price by a placement to insiders - the result is a massive dilution to all non-inside shareholders, a loss on the insiders original shares (which may have been bought at the original Australian IPO - was that at $0.50 - a massive loss as the equivalent now is $0.007c) but a very large new controlling shareholding for a very low price eg $18m cap raise at $1.00 will result in doubling of shares and so 50% interest in the company to the placement receivers .
Why does the company not release news? Aside from any reasons related to not upsetting the trial investigators or upsetting the FDA, it's because they don't want any news to raise the share price; they want a low share price!
It's possibly now a civil war - between the regular shareholders and the insider shareholders . Maybe it's time for a shareholder revolt!!
Who are these insiders exactly?
Where did the new CEO stand? Seems like there is no news released to explain the situation and his next actions, so I'm thinking he might be in favour of no news ie he might want a low share price.
So, did the last CEO get his salary, bonus, options etc so he would leave quietly?
