Short version: it’s being claimed that Bioware stripped out the “From Ashes” ME3 DLC (downloadable content) from the main game in order to make more money. There’s a bunch of stuff about code and a bunch of acronyms and whatnot; personally, I never noticed, mostly because I pre-ordered a physical copy of the game over a year ago after seeing what happened when everybody tried to download the Dragon Age 2 demo at once. That bit of foresight got me the DLC for free.
Anyway, I think that this is more redirected grieving for a PC than anything else. Or something.
