For starters, I really just have to outright laugh when people complain about the cost of games to begin with. Games are a frivolity, they always have been, so any discussion of bargains or values essentially break down right out the gate. If you think you're being nickel-and-dimed now, ask any SNK fan about the NEO GEO console. Sonic the Hedgehog was 50 full US dollars in 1991, and now I can get it plus every other game in the Sonic, Phantasy Star, and Shinobi series on a single disc for less than half that. Do I feel cheated? Of course not, because I like those games and no one forced me to buy them.
Second, look at it this way: I downloaded a demo of a game called Winemaker Extraordinaire. The file is several hundred megabytes, this being because when you actually purchase the game, you "unlock" the demo. I had the full and entire game right there on my hard drive, but I paid to use whatever the demo otherwise cordoned me off from.
If I'd hacked the demo so I could play the game without buying it, that's taking advantage of content they put out to earn a livelihood from. That's stealing.
Having the content on the disk just makes it so you don't have to sit and download it when it comes out. Yes, it's a bit of a dick move that EA essentially baits you like that, but that doesn't justify taking from them. If you don't like how a business does... well, business, then don't support that business. Hell, if you really had a beef with the publisher and wanted to stick it to them, send a check for the cost of the DLC to the developer directly.
