Yep, I'm getting that too. Full error banner says:
Error
The socket.io library could not be loaded from https://live.hexbear.net:8443/socket.io/socket.io.js. Ensure that it is not being blocked by a script blocking extension or firewall and try again.
Turned off ublock and umatrix extensions & firewall but still getting it. Looks like it's not a totally new issue.
Similar to what others said, it is about control. The US state has complete control over how the "algorithm" feeds people the narratives that the US wants to feed them when it comes to the major social media platforms. But not with TikTok. It is not a national security threat in the way they want people to think it is, but it is a national security threat in that they can't force their curated propaganda through it as they see fit, like they can with the other platforms. It's a propaganda liability.
