Reacting to "CDPR are heroes" fandom by constantly belittling them is a reverse reaction that isn't much more level-headed. Let alone when an objectively pro-consumer act is being ignored at best, mocked at worst.
Yes, this is a marketing stunt. An obvious one at that. So?
Marketing isn't an inherently bad thing, to be avoided. Is "marketing" the new boogeyman or something? A person who neglects marketing altogether is honestly a pretty poor businessman. Marketing is spread throughout years, not just the months leading to release (in which stage we already are, anyway). I seriously do not understand the criticism\discontent or whatever word that properly describes some of the cynical comments here.
I am not saying we should go through the roof. Hardly. CDPR didn't announce here that they'll be working on 20-hours worth of content for free. They are announcing small DLCs, most of which we don't know what contain, and how significant they really are. Is it a game-changer? No. Is it unusual in our gaming environment and is a kind act towards their fans? Certainly. Does it somehow come at the expense of the game's quality? No. Does it somehow come instead of CDPR marketing other, additional attributes of theirs? No. This isn't an equation with room for only one variable.
It's marketing, but not empty of content. Companies can choose what to market themselves as. So far, CDPR arguably has lived up to what it chose to market itself as.
