Does Google consider an example of Wall Street Journal whereUser who are not subscribed to WSJ do not see the full article and Users who come to the same article via Google search result link see the full article a violation of their webmaster guidelines and does this affect SEO? This is a form of cloaking but is required by Wall Street Journal to make money by allowing Google to index their content by showing it the full article but not showing the full article to users who have not paid for it.So my question again is, does showing a different page than what is shown to users who are not privileged to see the page affect SEO?
Does blocking content for some users and showing it to Google for indexing affect SEO

In general, showing different content to Google than is shown to users is regarded as cloaking. It's a violation of Google's guidelines and so, yes, a potential problem for SEO.    However for subscription sites, Google operates a number of systems that allow for subscription-only content to be crawled and indexed.One is first click free, which allows non-subscribing visitors a free view of the content. The other is a subscription label on the search result.  Both offer a compromise between the publisher's desire to promote the content and Google's desire to maintain good user experience by ensuring users can either preview the content, or know before clicking that it's inaccessible without a subscription.
