What toot said. Substack is not really giving you news. It has some very good writers, but they're not out there developing sources, breaking stories, conducting investigations, or doing primary research of any kind mostly (except in the instances where a research scientist is also a writer). It's largely people with some expertise and writing skill reading the news and giving you their take. Someone still needs to actually produce the news for the writers on Substack to even have anything to write about.
