I highly doubt they do. The developers might wish to, but by the end of the day their reality is likely: "You have x amount of time to produce y minimum quality of product from z amount expenses. Make it work or get demoted or worse."
Deadlines, deadlines, deadlines.... Quick fixes, quick fixes, quick fixes... Money, money, money... Rinse and repeat. Quantity over quality.
At what point? It all rests in the money. They monopolize on the Sims since no other company has created a game quite like it. A competitor comes along and takes away a lot of their fanbase would probably get them interested in doing more than what they do now. A protest via not buying until things are fixed and the quality goes to at least standard might do something, but that depends on how much of a cash-cow the series is for EA.
