google at least lets you know whether a "subscription" is required. Moreover's feeds have degraded badly for at least a year as (among several other reasons) the actual link doesn't usually indicate whther the article if "open" or requires registration/subscription, (As well as the fact they fill up a lot of their categories with news feeds that pay for exposure - for example the "management" feed is full of news-cum-press releases from a few leading management consulting companies - to te extent that almost 70% of items come from there.
