Have no doubt this will be unpopular, but I think LinkedIn is right.
Most news sites publish to the world. But scraping a news site's content and monetizing it yourself is not ok. Legally, it violates intellectual property law. But laws aside, I assume most people would agree, if someone spent the time researching and writing an article, they should have the right to monetize it and nobody else.
In this case, IP law may not apply, but the concept is the same. I don't love LinkedIn myself. But they spent the time building a platform for collecting that info. I don't see why it should be OK for other people to scrape and monetize it.
