Plain English like the price guarantee against "full price" which actually means discounted price?
There's been plenty if different interpretations and assumptions of what this offer actually entails, mainly due to a lack of clarity / incorrect wording. To put all the blame for that on fans is rather one sided.
All in all, with the clarifications, I think it's a great deal for anyone who would have renewed anyway, and potentially a good one for anyone undecided.
