The people behind the information are the resource, and finding a viable way to keep that resource accessible is a challenge these days. I read a lot online, but there is some work that I simply must do on paper (editing and proof reading). I can't sit and read screen after screen (a book) on screen either. When I read long newspaper articles I'm fine, but if I'm looking at something longer than that, like a 20-page PDF document, I print it.

PDF documents are meant to be printed (they appear on screen and in your printer the same as the original printed page) so you can see how many of these journals save themselves the paper and distribution costs by making the PDF available to subscribers to print or save. Lots of places do that. If they don't want to bother with vetting subscriptions then they need to look at the ad route for income. It might be like Consumer Reports, ads are inappropriate (though the entire thing is an ad). It'll be interesting to watch.
