I dunno if there's a stamp for this saying but I doubt it.
Anyway, if you're unfamiliar with this saying here's the summary.
Movies, video games, comics, books, whatever are all part of a business, at least in terms of the big name stuff (I'm not talking about indie created things here). And as such, very often money-making schemes are implemented to try and see what consumers are will to buy and pay for.
In a more basic way of putting it. If a video game comes out that has the bare minimum of said type of video game should have, or is a very poor game just in general, or it's lacking a large amount of features that were advertised or perhaps has a bunch of unnecessary features; it doesn't matter HOW much people complain or protest or leave messages to the developers on their websites or youtube or facebook. The fact of the matter is that if the game makes MONEY and people BUY it, then that is all the publishers care about (I am talking specifically about the businesses in charge here, not the creatives behind the actual making of the game). Companies are smart. They are willing to take some bad press or negative feedback as long as, at the end of the day, a profit is made.
So, the responsibility lies with the us as the CONSUMER to let companies know what we are and are not willing to accept in our media. And the only way we truly are able to send out message is to refuse to pay money for something we are unhappy with. You can complain about the new crappy reboot movie until you're blue in the face. If you go out and pay money to see it in any fashion, you are contributing to more of the same being made in the future.
Using money as the consumer's 'voice' DOES work. More than likely the only reason the Xbox One was adjusted and features tweaked after it was first announced was because Microsoft noted the lack of pre-orders and realised things needed to change. The same goes for Nintendo and the lack of sales for the Nintendo Wii U. The lack of 3rd party support on the wii obviously didn't matter to them because they went ahead and made the wii u. But now that sales are WAY down on the wii u they are actually announcing that they feel they have failed to deliver a product up to people's expectation.
Basically the lesson is, if you're unhappy with a movie or game or comic DO NOT BUY IT. It's as simple as that. You are NOT helping your favourite franchises by buying mediocre releases. Even if you are a complete Die Hard fan, you should not let your love and devotion contribute to the deterioration of your favourite brands/stories/characters/games/movies/comics/whatever it is.
....that wasn't a SMALL summary at all 8D;;
