Personally, I think the entire entitlement thing from gamers is getting out of hand because of three things:
1. the ever increasing cost to make a game vs the price they're currently sold
2. expected standards of gaming (and electronics in general) that are getting higher with each generation
3. the name "gamer" refers to someone who indentifies him-/herself as playing games
Lemme go into more detail on those...
Inflation means that pretty much everything tends to become more expensive over time. Think of 10 years ago (or ask your parent if you're young) how much an apple, a bus ticket, coke cola, mars or a loaf of bread was worth back then. It was way cheaper then, yet the quality was exactly the same. Nobody complains about it, though. It's just the way things are (you can always choose NOT to buy these things). Electronics do NOT follow these standards. Rather the opposite. Moore's law indicates that processing power doubles every 18 months, and for some years, it has passed the point where extra processing power was absolutely needed for daily work routines. The result is that the not-so-state-of-the-art machines become more attractive because they are cheaper. And not only that: ease-of-use, long term quality, amount of electricity used...all those factors are starting to calculate more into what makes something quality. And that, in turn, changes perception of what to expect from a modern pc. It not only has to be fast, but quiet, all-round, have a good graphics card, and so on.
Games follow that same trend...or perhaps it's more correct to say that they're leading the trend. In any case: games have grown as well. Not only to keep up with Moore's law that sort of pushes all developers into making use of awesome graphics (if they don't do it, another developer will), but on other standards that we have come to expect over the years. RPG-elements, cutscènes, multiplayer, a story*. This puts developers in a very uneasy spot. On one hand, it takes much more money to provide all the things gamers have come to expect over the years while on the other hand the price they're willing to pay is lower than ever. And that last one is pretty hard. Piracy and free games always had an influence, but I doubt it was ever as big as it is today. Back in the old days, it was pretty common to just go out to the store, buy a 70 bucks game** based on its cover only to find out it sucked. But you played it nonetheless because you payed money for it and second-hand sales weren't as common or easy as nowadays. The end result: you hated it less (or even liked it) BECAUSE you spend all that money on it.
Finally...there is this thing called "gamer". We identify ourselves as "playing games" and take them seriously. Way more seriously than we should be. When we go to a restaurant that isn't as good as we hoped, we simply go elsewhere. But when we spend roughly the same amount of money on a video game, that is PERSONAL. It HURTS. Even more that we are somehow to blame, as with all the previews, reviews, demo's, shareware, youtube-vids and so on, we should have KNOWN BETTER. And because we are gamers, that hurts on a deep personal level. And that means we get emotional about it and do things that get...pretty irrational. Instead of just "not buying" the game anymore, we tell the entire internet how bad it is, tell our EXPERT VIEWS (tm) about what is wrong with it and by God, we do it as if we're the director-CEO-vice-president of the company (and the universe) themselves. I admit that these sorts of rantings are also somewhat caused by the anonymity of the internet***, but still...
I'm into S&M. And while that by itself has nothing to do with gaming, I see that same sort of identifying in my community. Believe me: if you have your opinion on how another S&M guy or girl does things, you WILL get a lot of negative feedback. The thing curious people bump into the most is not so much how we aren't the scary weirdo's popular media make us out to be, but the amount of political correctness you need in order to talk to people. Because it is IMPORTANT. Something silly as how to address or what I might or might not like and in what context...the average S&M guy/girl can talk for hours on how (s)he is not what someone else thought (s)he was. Much in the same way a gamer can spend many hours telling how bad some games are (the Spoony experiment, anyone?).
But I digress...the entitlement thing. Lots of gamers seem to have this worry or primal fear that the games they have come to love (or are downright addicted to it) will come to a halt. They fear that the policies companies start to practice in order to keep their books in the green will ruin the fun they have in gaming. And to a degree, that might be true. Games are changing. They follow trends, but the main factor is and will always be that they need to make a profit. Companies that can't afford to keep their programmers, artists, musicians, writers, ... working will stop doing so in the end. Or change their business plan that will make them a profit. They know that no matter what they do, some people won't like it. That's normal. You can't have a million-people audience and please them all. You simply can't. Companies can't simply cater to the one who wants the same game over and over again. I mean...nintendo is trying exactly that and not doing so good with it.
*of course some genres always had a story-focus. But nowadays even genres that never revolved around it (FPS'es are a prime example) suddenly need voice acting and cutscènes or they'll be seen as "less quality"
**this is adjusted for inflation. The real price was actually somewhat around 40 bucks.
***compare Angry Joe's first rants on the xbone with his face-to-face interview with Major Nelson. It's not as easy being that mad about it when faced when the person doesn't look as evil and cunning as they are in your mind's eye
