None. The 70 dollars paid up front was to pay for all this supposed free stuff and patches you speak of. That's what those 70 dollars is supposed to be for. To pay for development costs and upkeep. But somewhere along the way developers got continuously greedy and gamers let them. Oh well. Btw, the poll is clearly biased in its options as there is no choice for 0. With this logic we probably owe Sony, Microsoft , Nintendo, etc... A lot of money for all the free updates they give us to our consoles and operating systems. Or to bungie for simply using their forums and apps, and they update them still with different features... And they were free... Unlike destiny, which we paid 70 ish dollars for minimum.
