A quick google search "substack site:theverge.com" will reveal that theverge hasn't written a single positive article about substack. Most posts are implying you should avoid substack.
The whole article is based on "this one guy switched to ghost" type of evidence ... no data, no stats.

I loved the open web quote: "The more important thing is that we have a home on the open web that we control, and whatever anti-creator changes Substack is forced to make in the future to live up to its valuation we won't be affected by."
To me, I always said to have your own website and domain. Because platforms come and go. I have experienced it myself with Medium, WordPress, etc. I wrote a little more about "Why I think to Have Your Website" at https://www.ssp.sh/brain/why-have-your-website/ (in case of interest)
