Thanks for the feedback! We are not part of the core pdf.js team. In regards to pricing we found that for some companies creating their own viewer requires a fair amount of upfront resources - after trying to create their own viewers they realized the time to build and maintain was not economical. The other big consideration is the opportunity cost of sinking developer resources into a viewer that is not a core differentiator.

It's super misleading to call yourself "PDF.js Express" then. It sounds like a paid extension to PDF.js. You should rename the product.

Right there with you. This is straight up infringement and confusing for everyone involved. This should not be allowed in the slightest. Highly disingenuous for them to do this.
