I am confused but it seems most other instances besides feddit.de works quite well. I moved my account because the federation on feddit was (is?) broken. But yeah this was a major change and I guess most instances are sidecar projects and not professionally hosted nor maintained. I would definitely pay for a proper hosted and maintained Lemmy instance.
Oh this remembered me of that I do have an account since last year and just used it to argue with some fan boys about if Bluesky is full FOSS or not (it’s not)
