Are you saying that people should be reading EVERY news site and then post what they see from any and all sites that make good content? How do you recommend they do that labor, use a news aggregator? Are you daft? This is how news aggregation works!!! Some individuals with real lives become deep consumers of a few specific news sources, select the best content they find and submit to aggregators like Lemmy. You and I benefit from 2 dozen of these people, each with only a handful of news sites they can review in their limited time and because there's 2 dozen of them we get news from 30 - 50 news sites in our feed.
