I really hate to break this to you, but making games is a business, so making money is always the number one priority. It was never about delivering the awesomest funtime experience to the user because the user deserves radical video games. Honestly, calling a business "greedy" is one of the most naive things I have ever read. They are trying to make money with their product. This is capitalism, not a charity.
DLC and microtransactions potentially add value to the product after sale, even if the sale was second hand. That's the reason every major game needs it.
There are many odious decisions that are being made now in order to deal with the used game issue. Adding grind ("RPG elements") to a game that really doesn't benefit from them, for example, is an attempt to keep the product in the user's hands long enough to reduce the primary sale window used marketplace. Same thing with mind-numbing collection mechanics. Appointment mechanics aren't far behind, all because ARPU is becoming far more important than trying to make all your money off the initial sale.
So, even though you may not realize it, the prevalence of the used game market is dramatically affecting the games you play. If you want more Zynga-style compulsion loops and monetization pressures designed into your console games, then this shouldn't bother you at all. If you don't, than you should be a little concerned about the direction the industry is heading.
