Maybe this isn't in the international news, but one of the prosecutors in this case specifically said they understand e2e encryption prevents FB/WhatsApp from handing out the messages but they want at least the IP addresses so those can be followed up with the local telco companies to identify who is the subscriber. It's business as usual and, AFAIK, FB/WhatsApp has been denying all requests equally. There was specific mention of "no cooperation at all" which would be a subjective statement saying the company is not willing to find ways to help this criminal case in good faith.

I think the term "in contempt of court" is what is happening here, although my vocabulary for law terms is limited.
