The "Final Hours" app? It suggests that they didn't devise some intricate plan while they were writing the ending.
I think we tend to get tied up in conspiracy theories. From the statements Casey Hudson and Mac Walters made, I think they believed they had written a fitting, bittersweet ending that the fans would like.
My guess is that they still don't quite have their heads around just how much the ending is reviled, plus it's a big deal to change the endings in a meaningful way. It's costly, and they're certainly trying to figure out what the best business decision is.
My hope is that they'll see that the longevity of the franchise and the enthusiasm of their fanbase mean a lot more than the short term profits. If they do nothing, they'll lose market share from their most devout fans, make less money, and the fans will be left unhappy. Doing nothing is lose-lose. Doing something about the endings is win-win.
