I don't believe it either. This advice has probably never been less true.

Perhaps there is just a certain kind of Substack journalist who chooses some dubious piece of conventional wisdom every Sunday to sermonize about.

I don't know that I would characterize the typical Substack writer as a "journalist."

It's just opinion blogging.

They get paid.

That's why they write it on Substack not Blogger or Wix.

Still not journalism. Just paid opinion blogging.
