I share this sentiment, and I admit I am not entirly aware of the Substack situation tbh. The issue is that these people, often very good journalists need a platform that generates revenue for them. I am not American, but find that people like Kuo, Jennifer Rubin, Robert Reich and Joyce Vance give valuable insights on American politics, and “sound bites” that can be share. But they need lir financial support to do this.
