No. What I am saying is this. Say that a person is being investigated for some felony activity, and has data relative to that activity stored in the cloud. That person also thinks that by having that data stored on someone else's servers, that since it is his data, it would be covered under the 4th amendment to the US Constitution, requiring LEOs to get a warrant to get to that data.
That person would be wrong. Since it has already been proven data in the possession of a third party (Facebook, Apple, Amazon, any company owning cloud-based services) is owned by that party, the LEOs would only need to subpoena that third party to have that third party give them that person's data. No warrant required.
Now.. replace that person with you, and that data with your vault. That would mean that if the LEOs were going after you for something, and see that your passwords are in a vault in the cloud, they won't need to go to you to get your passwords, as you could easily exert your 4A and 5A rights to defend yourself from such actions. Instead, they could go to that third party with a subpoena, get your vault, and try to get your passwords that way, without you ever having any say about it.
