This goes right to the heart of the issue so I felt it was worth highlighting: Who cares if they lock out their content? There are literally millions of news sources on the Internet, all (hilariously) copying each other's posts on what's trending in news, with often amusing (or horrifying) results when the stories are wrong. Oh, I can't read this story on Yahoo? Well I guess I'll just have to pick from the ten thousand freaking other copies of the same information available elsewhere.
We have TOO. MANY. NEWS. WEBSITES. The ad space isn't worth shit because the same ads are being pushed on millions of pages many times over, and the public is so desensitized to them at this point that the click rate is dropping like a safe.
If you work for one of these publishers, get a new job. Fast.
