They all offer DLC; depending on the game, some, all, or none of that DLC is included:

- Burnout Paradise: offered version contains all DLC

- Crysis 2: offered version contains all DLC

- Dead Space: tons of weapons DLC, not included. They're effectively cosmetic or so overpowered it's like buying cheat codes.

- Dead Space 3: tons of weapons DLC, not included. Like above, they're either cosmetic or shootable cheat codes.

- Medal of Honor: missing the DLC map packs

- Mirror's Edge: missing time trials DLC; DLC is incompatible with the Steam version

- Sims 3: contains a small fraction of the available packaged DLC; game is centered around micro-transactions for things your home (i.e., there are countless items not included).

- Battlefield 3: missing the DLC map packs

EA, of course, profits from DLC purchases not included in the games on offer: they're not sold through the Humble Bundle.

BF3 has several DLC and I Origin would get 100% of those purchases. In fact BF3 was recently a free PS+ game; I'm guessing with the idea to drive people to buy the mulitple $14.99 DLC packs
