E2EE has been implemented since 2016, and turned on by default as of May 2020. Uploading contacts is strictly optional (and is missing on some platforms like Android currently, as per complaints elsewhere on this thread). They're used purely to discover which of your contacts are already on the platform - the privacy policy can be found at https://github.com/vector-im/policies/blob/master/docs/identity-server/privacy_notice.md#22-how-does-it-support-contact-discovery https://github.com/vector-im/policies/blob/master/docs/ident...
