- Signal's Sealed Sender feature provides one-way anonymity but fails in two-way communications.
- Metadata like IP addresses can still reveal communication patterns despite Sealed Sender.
- Signal requires phone numbers, which can be tied to identities, compromising privacy.
- Delivery receipts in Signal automatically create two-way communication, negating Sealed Sender's benefits.
- Alternatives like SimpleX offer better privacy by not requiring global identifiers.
