If they go private with investors from Abu Dhabi all I can say is shame on them.
Greed would therefore be the main motivation for all the silence!
There not going to make the world a better place if a bunch of rich people in Abu Dhabi take the spoils of all the investment dollars used to fund and study the powerchip.
Where was Abu Dhabi when the power chip was in it's infancy? The US government help study this device.
By allowing us the unvestors to benefit lies the potential for further investment in projects similar to theirs.
This is a cycle broken for the purpose of lining someone's pockets.
