Are there actually that many "reporters" forming newletters? Most of what I see are opinion columnists forming newletters and doing zero reporting. No calling sources. No interviews. No digging into documents. No investigative anything. Looking at the various substacks mentioned I see a lot that are "people writing their opinions on things they saw on Twitter". I'm not sure the world needs more people spouting opinions on a weekly basis. Heated is the only one mentioned that seems to do any actual reporting.
