Please stop holding the industry to some ridiculous national security level standard. Despite what die-hard fans want to believe, it's not that complicated or mischievous. Bethesda wants to limit the flow of information re: the review embargo. They don't want to see huge Tomb Raider, Battlefront, Insert AAA game here, ads all over their day to shine. Would it be the end of the world? No. But they are a publisher and it's their job to minimize that shit.
If that's the case I still find it gross. Just because it happens all the time doesn't mean it should be okay. The simple fact that there are huge AAA ads on the front page of these supposed "unbiased" review sites is questionable to begin with.
