This Copy right stuff is out of control.
Newspapers want hits on their web site so that they can sell advertising, perfectly understandable. One way (ugly) around this problem would be to place at random, an ad from a list of news paper advertisers as the first reply. I think most paper would go for something like that. It would help them and would not be a terrible thing for FR. Someone might suggest this to Jim.
Hey.. I trademarked those two words used together.. You owe me $0.12 /kidding
A more appropriate action would be to have the website launch a popup to the "source link" when the thread is launched. Locally store the text of the article (archived against future tampering or deletion) but require the source website to launch (at least the toplevel domain) in order to read the locally stored text.
Permit all discussion of the article to proceed without popups (since at that point it is just excerpts from the article and FR posted original commentary).
The only time you would see a popup (to the original site) is when you chose to read the FR hosted text of the article itself.
This would slow down browsing just a little bit but remove none of the functionality of FR.
