While Signal messages might be e2e encrypted, people tend to forget that the platform collects phone numbers of its users, which can be used to identify people.
This makes Signal an effective metadata collection tool that resides on a central server in the US.
By cross-referencing these identities with data from other companies like Google or Meta, the government can create a comprehensive picture of people's connections and affiliations.
