It appears that x.com is being transformed into WeChat.
The team there RUTHLESSLY penalizes outbound links, so that’s why nobody sees your Substack posts on X.
In order to get people to see your posts, you MUST not link to anything.
With the “everything app” they’re trying to create, the team at X has embraced an anti-competitive stance.
It’s the opposite of what a “free speech” company should support.
