200,000,000 shares authorised for issuance
145,000,000 shares issued to date
let's estimate 15,000,000 shares assigned as options
that's 160,000,000 fully diluted
leaving 40,000,000 shares available for issuance as poison pill
If that happened, there would be ZERO shares available for equity raise as needed. No money to fight off potential hostile takeover. Also, with the 40,000,000 share dilution people would still trade stock, stock price would be significantly lower from the massive dilution, so in effect a takeover attempt could ultimately be successful at a lower total price.
If the poison pill was done when stock was higher and outstanding shares were significantly lower there'd be better chances of it being effective.
Your statement about no shorting is not accurate. Many shady brokers exist, you can find SEC actions against them frequently.
