I'm going to predict Apple does not cave in on this and comply.
Apple has reportedly been ordered by the UK government to create a backdoor that would give security officials access to users’ encrypted iCloud backups. If implemented, British security services would have access to the backups of any user worldwide, not just Brits, and Apple would not be permitted to alert users that their encryption was compromised. https://www.theverge.com/news/608145/apple-uk-icloud-encrypted-backups-spying-snoopers-charter

I’m going to predict they work out an agreement to share the data and we never know about it.
Oh man i hope that is not the way it goes. Apple was my Bitcoin to Windows Fiat in the 90s - Tim Apple is no Steve Jobs, but I'm so rooting for them to keep Privacy a competitive business advantage in the long run and not cave in.
They basically already have, they just have not implemented it yet
