The bust was actually covered by the german police via Twitter the Friday after the raid (2019). Media outlets allover the world reported about that case too ever since it happened, without delay.
In cases big like this, where over 600 police officers are involved (in the middle of Germany), it is difficult to keep it hidden.
I highly doubt that this case has anything to do with dread (if anything, that they hosted their servers) and I think the rumors are just hearsay and based on wrongly connected information
