The fact that Damon would even accept funding from Abu Dhabi or ANY oil interest speaks volumes.
It strongly suggests that he was bought off.
It strongly suggests that he KNOWS there is no problem with fracking.
What this means is that Damon’s opinions are based purely on who is greasing his palm.
I'm not so sure. Fracking is widely accepted as bad in the liberal community. Damon most likely looks at the script first before he worries about who backs the production company. Besides, the ultimate source of funding might not be immediately obvious to the actors.
