> there is basically no incentive for them to fight the summons
Ehhh, seems to me a cloud provider that wants to back up my documents, communications, photos, passkeys etc has a very strong business case for ensuring the data is as safe with them as they would be in my own home.
They have an incentive to maintain a perception that it is at least as safe with them as any of their competitors. That isn't quite the same thing as having an incentive to protect your privacy.
Sweet summer child.
