The network effects of substack seem pretty weak. Authors can use their own domain name and export a list of their subscribers any time. Their value is in providing software that is sticky for writers and solves a lot of the problems of creating and retaining an audience, which they seem to be doing pretty effectively. For better or worse, I don't think substack has much influence on the broader ecosystem either way; it's all down to consumer demand.
