Was this never broken because the enigma@home community lost interest? It looks like their last forums posts were from 2019
For all we know, some bored German submariner sent garbage over the radio as protest; this message was sent two days after Hitler committed suicide, 7 days before VE day. (8 days if you're of the Soviet persuasion) Morale and discipline has a tendency to break down under those circumstances.
Or it could be a transcription error. Modern cryptanalysis tends to be more resilient to transcription errors; one character wrong is gonna be ok, one character inserted/deleted will tend to produce two messages, one with garbage after the insertion/deletion and another with garbage before it. But Enigma messages were...terse, so a half-successful decrypt that gets half garbage and half plaintext might still be recognized by the cryptanalysis algorithm as the wrong key. I expect there would have to be at least two transcription errors to cause both the original German commo to be unable to decrypt it and modern attempts to fail.
- 6 days after US and Soviet forces linked up bisecting Germany
- 1 day after Hitler's suicide
- 5 days before the unconditional surrender of the Flensburg Government
I may be biased, After reading wheel of time, nothing seems too long anymore!
It is a decent book to read once though.
Animal Planet made a fake documentary about Mermaids (a somewhat hokey one at that), with a disclaimer that it was a work of fiction.
Despite that, it's convinced a generation of fools that mermaids are real.

But back to the internet. Plenty of youtube clips from this program where commenters are insistent that it's evidence that Mermaids are real. And comments linking to the footage of the disclaimer, and resulting dumb arguments. Still! In 2023!
I love a bad/earnest low-budget movie. I think they are often much more revealing about the nature of culture, cinema and art than -- to pick a single counterpoint -- really anything in the MCU except Age of Ultron [0].
There were plenty of things in that to like. I watched it only recently, I'm glad they made it, and I hope the people who make it continue to reject the big bucks.
[0] This is a hill I will die on. Almost everything in the MCU is pointless dross except James Spader as Ultron.
See also, Finnegan's Wake. For instance, here's a nonsense claim that sounds plausible: Finnegan's Wake is the best book about the Irish Civil War. You feel the frenzy and delirium of the lucid somnambulism that comes with insomnia on the battlefield. As foggy and vivid as war, the words carefully balance the interregnum between the forbidden, forgotten and forsaken laid bare as poetry. Nothing is clear and there is no closure. It shows how hard narratives are to cobble together using shattered pieces. The deconstruction of the language is married with the deconstruction of life as belligerents fight over conflicting dreams.
Better starting hook that the Last Resort series (US nuclear submarine with intercontinental ballistic missiles refuses weird orders, is fired upon by the US Navy, and decides to occupy a fictitious island).
They could be scored by decrypted content matching structure of priors and context. Along with char difference from the encrypted message on record.
"In the old days, if someone had a secret they didn’t want to share, they went up a mountain, found a tree, carved a hole in it, and whispered the secret into the hole. Then they covered it with mud and leave the secret there forever." - Wong Kar Wai/In The Mood for Love
An enigma message would be typed in to the machine and the output characters written down on a piece of paper, then the message would be transmitted over Morse by hand, transcribed to paper at the other end, then typed through the correspondingly configured Enigma machine to obtain plaintext.
IIRC a transmission started with the rotor settings for the rest of the message encrypted using the daily setting and sent twice. Even sending this much, such that both copies communicated the same setting, would reveal that Enigma was compromised, I think.
Once you have a few months experience in Morse code you are able recognize who is "talking" by the way they operate the key. The radiomen would know pretty quick if some new guy came started sending them bogus messages.
