I agree. I would definitely love to integrate (and improve) this as part of my SAAS product, and I would spend way more than $400/year in effort on it. However, I can't possibly use or buy this as is, because it isn't open source. For comparison, my company pays for the CodeMirror "moral license"...

$400/month is what PDFJS express is charging. $400/yr would have been a little difficult to swallow too, but this amount is just absurd for a product where most of the underlying technology is open-source.

Pdf.js Express is US$375/month, or US$4500/year.

No, it's $440 / month if you look at the actual pay-per-month option.

Wow. This will be a good example in GPL versus MIT license debates...
