This thread inspired me to stop procrastinating and deploy my own instance. On a brand new Debian 12 install (an LXC container in Proxmox), the process is absolutely simple and painless.
It's not about standards. It's about how "Meta" is going to use the data they'll collect to manipulate and advertise to you in insidious ways. They don't want to cooperate with the Fediverse, they want to control it. Those are the issues and the source of negativity.
On Kbin, hover the mouse over the "more" menu under the post/replies and click on "copy URL to fediverse", that will send you to the original instance.
It worries me that all those communities moving to Discord will one day suffer though all this all over again, once Discord enshittifies and drives them out. Relying on a closed, proprietary and centralized service for user-generated content is a bad idea, as we all learned already.
