Of course, Jon is correct when it comes to taking direct quotes from premium articles.
However, taking INFORMATION from a pay site and then discussing/posting it...is in no way, shape or form a violation of the law.
Do you actually believe someone can post something on the internet and then impose a legal sanction to prevent people from discussing the information?
No way in hell. The ethics of this are another issue...but in terms of legality, unless you have some sort of court ordered sanction...once information is given, you cannot tell people what to do with it.
Unless i missed a post I do not think anyone has questioned it being a legal issue.
