If you think that Disney is "greedy" and no longer shares your values, then take action: Sell DVC, boycott Disney, and take your vacation dollars elsewhere. Everyone has the freedom to do that.
If you state that Disney is just looking at the bottom line and appeasing stockholders by keeping their stock value high, then you are absolutely right. You might also consider doing what we have done and become a stockholder with Disney. You may find that this certainly helps take some of the sting off of price increases!
If you are simply disappointed in price increases (like me) but still are a fan of Disney then you reevaluate your vacations and determine which AP is best for you, or even whether or not an AP is your best choice. Same holds true for TIW. (In our case, the gold pass works, this is an increase of just under $20, and TIW will probably not make sense for our family).
