The whole of Nostr isn’t your feed. Just follow the ones you want. I like to see a variety, including seeing some of what my friends may be getting fed. I can process it myself. But these folks that are sharing various news stuff from various sources, including msm, are fine. showing and sharing a broad sampling is just fine. You personally can always mute and unfollow the ones you want to hide from. But I don’t seek out news elsewhere, so the trickle of notable items is welcomed.
