Whatsapp doesn't have it though. If they did they'd be legally obliged to share it. Currently since they don't have anything they can't share anything hence the "uproar".
I imagine Facebook would love to be "forced" into stopping E2E as they could then mine the data happily for more targetted advertising.
Edit: I may be wrong it looks like they could potentially still be storing metadata. As such I would expect the government to have access to this. So why don't they force the person on the receiving end to reveal the message.
yes they are storing the metadata, which is what i am referring to regarding the information sharing. it's even in the WhatsApp ToS. And it's the metadata which is more useful not the contents of the message itself.
Steganography has been around for ever and even if the encryption was broken, would most likely to be in place to protect the conversation anyway rendering breaking encryption often utterly pointless
there is absolutely no logical reason why the government would need this
