I dint get how this is rude, it would be trivial for THE COMPANY to add a few lines to their server configuration to redirect all incoming traffic from anywhere (or even just HN or Reddit) to redirect seamlessly to the non-print page that has both the ads and a print button....but this site hasn't done that (yet).

I don't think it's really that big of a deal. If it was a subscription service we were all bypassing without paying that's one thing, but this is just another page on their public website like anything else.

If you don't want people to see it, don't publish it online.
