I've been looking at Substack with the eyes of someone who has lived through the enshitment of Quora, Medium et al, and realized there are never guarantees with any such service. Apparently I owe them money and attention, and they owe me nothing. I will never get long term what I joined a service for, so today I simply do not commit. I never committed to Twitter, and I'm glad. I want to share content, I setup a ghost site. I want to read content, I use RSS and also read what I can for free. That's it.
