So the idea is to get people to install extra software on their computer which restricts their ability to do their jobs? Sure, that's going to become a big hit.

The file they have for download is close enough to a standard PDF that the standard Ubuntu PDF document viewer will happily open it and allow you to print. So nothing to worry about here in terms of accessibility in Linux, though I'm guessing it'll annoy Windows users who'll have to rename file extensions.
