Of course, the big question is whether you can keep the Substack email addresses. Otherwise you need to hope your readers see on social media your new home.
I think they're primarily bungling it up and not actively trying to enshittify, although I'm not well-placed to judge.
It proves the platform, that offers a high concentration of high average writing quality blogposts and a reliable trusted platform (For readers), has more value for readers, than some particular writer's writing.
This whole paid-blog space didn't even exist before substack, except for a handful like stratchery. So clearly its substack/marketplace that made things possible, not the writers. So writers should examine their egos before they complain this way.
Its like the indie game devs who whine about steam, forgetting that before steam, the PC game marketplace was a nuclear wasteland dominated by piracy and MMOs.
I checked and "statistics" includes email addresses.
