Ask HN: Why Medium fell out of fashion?

I'm a long-term HN lurker and I don't visit here very frequently. In my memory there were a lot of articles hosted on Medium. I suddenly realized that they're a lot less common than before these days.

What happened? Why isn't Medium cool any more? What's cool today, self-hosting static blogs?

Not for me. I use it extensively.

too many low quality spammy articles

too many restrictions on author speech

annoying paywalls

failure to stand up for authors , support authors

Substack, on the other hand, supports authors, gives authors full control over email list and paywall, opposes censorship
