You are given equal treatment, you paid for the game just as we all did and got the exact same DAI each and every platform has access to - plus or minus a few graphical features due to hardware restrictions. Your payment towards DAI did not cover DLCs, so you cannot argue unequal treatment for something you do not even own. It's not different from platform exclusive DLCs. A developer can choose to support whichever platform they want, you cannot dictate what a game gets released on. That you would compare this situation to slavery is disgraceful, and shows a severe lack of understanding on your part. If you think this will in any way negatively affect EA, you're only deluding yourself. This is a next gen game, and the developers chose to remove the shackles of 10 year old hardware in order to deliver on that experience. The arguments in this thread are driven by pure emotion, not logic.
That you have to resort to blatant lies in order to argue your point is pathetic. Do you work at MSNBC? Truly despicable.
No, we are not given equal treatment. We get dropped, supposedly due to hardware limitations. BioWare can't have NOT been aware ahead of time that old gen was not up to snuff. Yet they still released DA:I on old gen. They should have never released it in the first place OR put a damn warning label (how hard would that have been?). They gave old gen a shoddy game that hardly functioned for some, AND in order to make it work, cut content and (supposedly) made less than what it should have been for new gen. In my opinion, they've screwed over both groups with their short-term profit scheme.
What's worse, those people who bought the PS3/360 Deluxe Edition have reportedly been unable to transfere their Deluxe Edition save's (via the save importer) extra content, such as the Red Hart etc. Now how can you justify that? When they paid for their extra content on launch and can't even play it without buying ANOTHER Deluxe Edition PS4/ONE. 
That's fine if a company wants to consistently make unpopular decisions. They won't last long. They'll have chased, angered or whatever else people away and whether companies recognize it or not, they need customers to thrive.
And whether you recognize it or not, it's the customer that unltimately has the power, this is especially so when it comes to a "luxury" product. No one NEEDS a damn game. They game because they want to, not out of necessity.
Inequality is inequality. Sure, there are varying degrees, but to stand for any form of inequality is just... despicable. Is any amount of human suffering right/acceptable? Some of us are downright upset, broken up over this. It's a franchise we love, how can you expect us not to care?
Again, a damn gaming company possesses ABSOLUTELY no power over it's customers. It's customers are the only reason they are in operation. The people want it, the company provides. If the customers don't want it, or are chased off, the company dies. It's not a damn food processor, we don't eat games. Games don't provide anything but a distraction from the real world.
Logic vs. Morality, I'd say. Logic isn't always in the right.
Logic can be just as flawed as emotional responses.
