Classic Press is a viable fork that the Reg ignores (despite Situation using WP itself in one of its spinoffs and therefore having a perfect opportunity to report on CP firsthand).
It started with using 4.9, the last WP version before Gutenberg, now uses current versions with that removed.
It uses WP plugins.
The community hired its own devs, has its own forum. Far as I kniw, it doesn't sell hosting, but I haven't delved.
While it's fashionable around here to dismiss people who use WP, it's been around a long time and some now have decades of personal IP on their site.
At the time (2003?) that Carthik made his post about its beginnings, and switching to it, the other big choice was Movable Type, which was not run well.
Matt possibly had issues back then, his site's subtitle was Unlucky at Cards, which I thought rang weird, success tends to magnify quirks.
I see Classic Press as the way out. It's straightforward, uses the same bones.
If someone wants to put down their dismissively ironic waving hand and provide a way out that's better, my gantlet is hereby thrown down.
Until then, CP works and it converts a WP site to CP with a plugin and a few minutes, bye Matt.
