The biggest challenge to pricing based on volume is the exercise of tracking usage. In a typical SAAS product determining usages is fairly linear. For PDF.js Express because you would be deploying from your environment we would not have an accurate way to measure usage. Fundamentally I agree with you - you should pay for what you use. Unfortunately at this time we are not able to implement that effectively. Also keep in mind for some organization the value created from this product will far outweigh the final price tag.
