They have found out DICE is lying about Battlefront DLC? News to me.
No, more that they've found out DICE has done this sort of thing in the past -- included content on the disc that's basically locked away until the DLC drops.
To be fair, not ALL disc-related DLC is evil. Sometimes it's a question of assets and production schedules and QA. Like, you have a lot of the work already done, but there's fine-tuning left to be done, balance testing to run, optimization, more assets to be added later, yadda yadda yadda. So, you ship the disc with as much stuff as you can, but none of it's really ready til the DLC actually goes live. Thus, it looks like the DLC is "already on the disc" because people can find some files on there that relate to DLC, but in truth, what's there is more like a skeleton or building blocks for future DLC rather than the full deal itself.
This tends to be more true with early DLC, but they might include SOME assets for later DLC on the disc. If it could be proven that the DLC was all right there, that would be pretty damning, since the implication is that you already paid for the content, so why are you paying again just to "unlock" what's there? But I doubt anyone can conclusively prove that.
What I can, however, say from personal experience is that, in the past, "new content" has actually be more like "recycled old content." That hasn't been true in the more recent DICE games I've played (which stopped at Battlefield 3), but honestly, I have enough criticisms of DICE/EA outside of the DLC issues to warrant being cautious anyway. The DLC stuff is much less of a controversy for me anymore. I'm more concerned with things like game design, balance, having stupid unlock systems that turn the entire game into a metagame about unlocking crap and ranking up, and especially support.
Frankly, the support issues alone are enough to make me wary. Patches which break or don't fix an existing problem can linger around for at least a month, sometimes longer. I think Battlefield 2 never actually even resolved the "red tag" bug where friendlies would appear as enemies and you'd TK them. This has been going on since the first Battlefield game, too, where Patch A rebalanced something but screwed something else up, and Patch B took months to come out, then fixes it but introduces a new problem.
