Hate to break it to you guys, but, it definitely seems like reality finally caught up and the industry moved on.
This kind of information is extremely valuable and it's no surprise at all that companies would try to protect it from...well...the general public. Speaking from how they treat general reception to potential damage for a specific brand's image, it wouldn't be the smartest choice to let people with absolute no inside knowledge, to twist how a game did.
They're basically gatekeeping this information for inviduals that are so invested in actual market analysis, that would actually recognize how important this kind of info could be and therefore, pay for it even if it's locked behind a high paywall.
I gotta say, this community here is pretty infamous for making absurd and extremely mudane assumptions about sales in general. Of course, there's actual market insiders here, professionals that studied and get payed for this, but most people turned this into a weird type of hobby.
