FreshRSS already has web scraping abilities, and can grab the entire story for truncated feeds almost all of the time, if you add the css container class to the settings for the feed. What does Morss do beyond this?
EDIT After looking, it seems as if it does save the step of looking to see what the CSS class is. But I don't like the fact that all my RSS feeds then go through and are dependent on one single third party. Seems to somewhat defeat the point of self hosting. I'll just stick with FreshRSS alone.
EDIT AGAIN I see now that it is open source, but I still don't see value beyond what FreshRSS can already do.
