Entitlement has nothing to do with it, and you're introducing dangerous words to the debate. As a "gamer" (regardless of platform), it leaves a pretty sour taste in your mouth when you support a game day one and then watch others get "support" back from the developer before others...it's an equality issue...supporting all "fans" equally. The fairness doesn't lay in the eyes of the developer/publisher, doing so would be beyond short-sighted. If folks don't think that their profits would have been greater with such equality, on ALL platforms, then they'd also argue that 2+2=/=4. One of the largest intangible assets any company has is their public perception and reputation, and getting in bed with Microsoft helped neither in the long run; me still discussing it six years later proves as much.
Equate it to the car industry. How well do you think one car manufacturer would fair over the others if consumers buy the "luxury" model (Honda EX-L for example) afforded you early access to new features (paid or not), over those that opted for only the EX model, especially when they let you know AFTER you bought the car, while the entire time the car manufacturer knew this fact and it was painfully obvious they just wanted to complete the deal to "earn" your money.
How insane would it be for the same scenario across multiple car manufacturers where NAVTEQ offered Honda map updates six months to a year before offering them to Toyota. The backlash would be horrendous. Just because you didn't witness the public outcry, there indeed was one, and I assure you many shared the sour taste and still taste it.
Rockstar had zero issues making their games not only work but excel on the PS3. It's because they cared about their entire fan base and showed it, aside from their test of timed release DLC for GTAIV. No PS3 or PC gamer would have cared for Bethesda to have held the game until it was fully polished for their system. It was all about money in the short-run, making short-cuts to minimize their costs, and their relationship with Microsoft, and their covert public acknowledgement of such...all hurting them in the long run.
