alt Hacker NewsI have noticed some sites block cross origin requests to their feeds. It’s annoying but I just use a server now so I don’t care. I very much recommend RSS readers to use a server as it means you get background fetch and never miss a story on sites with a lot of stories like HN.
From the linked post, I think the point of fetching it in-browser is so that your subscriptions stay private. Idk why this is desirable, but if people want it, it’s nice to give them the option.
