I had cancelled my pledges and re-added them all today (and added one even). I know unfortunately a lot of creators will never get back a good chunk of their pledges, but I feel it's important for us to both revoke our money when a company makes a bad decision... and resume it when they make a good one.
Companies recognizing that good decisions make them money is the key. If they figure they're going to lose money no matter what they do, they're less likely to take our feedback into account.
