If they wanted to retain shareholder value and only wanted to dilute a little they could have put the a/s at about 1bil but they went to 5bil now why would they do that if they didn't want to dump hundreds of millions of shares a month ruining shareholder value hmmmmm???
An aspect of the bump was Manu keeping his voting rights. He has 10M preferred. Initially his voting rights were 25 to 1. So with 250M shares he would no longer control the company. They are now 250 to 1. So issuing more than 2.5B shares would risk his controlling the company.
Of course he could increase the authorized and increase his voting rights again.
