If entrapment is unprotected in a relevant jurisdiction, seized domains/servers could be used to disrupt or even unmask actors. Release a new dropper and make the payload build tool malware itself. Now these actors can't trust what they get from each other, even if they trust the person who is supposed to be in control of the service.
That would be a radical departure from the status quo of boasting loudly and plastering seizure pages up everywhere, and the suggestion here is that they are trying different things.
If a law enforcement official sets up a website offering to sell you an illegal product or service and you buy it, that's not entrapment. It's only entrapment if the police cause you to commit a crime you would not have committed otherwise.
