That video was annoying as shit to watch, but I agree with everything he said. I went through it stealth without killing anyone and planned on going through loud the next go through, but it is so weak I don't want to.
The only good story line in the game is a side mission where you are trying to discover who put the enhanced augs in you and that story is incomplete...clearly wanted to use it as a springboard for another game. I heard about the microtransactions, but I never noticed them in game cause I had all the skills I needed for stealth.
