At my previous shop, the reporters sometimes used to write stories based on press releases (I think they'd do some original reporting, but most of it would be based on press releases). I asked both of them to stop that practice unless there was no other way to write the story.
I can remember doing one story after a state senator switched parties from Democratic to Republican to run in a rematch against a guy who beat him in the primary. My original (pre-publication) story had quotes from four related press releases. By the time the story went to press, I'd spoken with all four of the people who sent press releases and had my own quotes. I even talked to the guy who made the switch and got his side of the story.
To me, this piece shows extreme laziness on the part of the reporter. You see the story in The New York Times, you call the people quoted in the story and get further details and make YOUR story better than the original. And don't let yourself get scooped again.
