This is the issue from the consumer point of view. For most people, it's too expensive to subscribe to more than a few (like less than 5) writers on Substack, and that excludes the newsletters that have the really high-expertised content (which tend to be quite expensive on a standalone basis, as one would expect). This makes sense for the writers, but as a consumer, it's very limited. I personally only read a few Substacks because I don't want to spend the money to subscribe to more than a few of them, given other subscription costs already being incurred elsewhere. No doubt many other potential readers are in a similar position.
