A lot of this material was previously available from Paizo as pdfs several years ago, though the quality was not always great. But Wizards changed their mind about whatever deal they had with Paizo and forced Paizo to not only stop selling the items, but to also remove the purchased items from the purchaser's libraries. I had purchased a couple dozen of those, some of which I did not have backed up and so have lost. I am not at all inclined to pay Wizards for them again.
