My personal take on this, that if CDPR want more positive PR, they should use crowdfunding for expansion packs, not pre-orders. It's a more direct connection with the fans as well as a better approach (investment rather than a loan).
Personally I think that would have backfired more, I know I would have complained at least. We know they have the funds to make it themselves so why ask for handouts to make it instead? Crowdfunding is good when it goes right like with Pillars of Eternity as a recent example, but it has been abused too much that I actively avoid it like the plague.
