I agree.

The BBC do a similar thing with their football news roundup from the daily papers with "<short overview> <paper name> - subscription required"

This doesn't stop people who do subscribe to the site from reading the content linked to and gives a heads up for people who don't.

The Samsung story isn't exclusive to the WSJ and there are plenty of other free to access news sites that would have been better for the submission. If we ban paywalled sites entirely it would prevent submissions of exclusive content (which could be an interview or journal)
