The respectable ones like Signal have nothing to hand over because either it is E2EE or they just don’t profile you at all. If the mom and her daughter had used Signal instead, Signal would’ve complied and only been able to serve the court the metadata.

Facebook neither encrypts the data nor does it only take what’s given to them by the user. There is so much non-consensual data harvesting happening on that platform, that they claim their users agreed to, when no one actually did, since their TOS are such a mess and are constantly being updated.

Just like IRC, for example.
