HushChat is not vulnerable to the above vulnerability because there are no delivery receipts in HushChat protocol. When Alice sends a message to Bob, she has no idea if or when it's ever delivered to Bob's wallet or if he reads it. This is a feature, not a bug.
Signal is also increasingly trying to be a (https://signal.org/blog/introducing-stories/)["social media app"] and encouraging people to leak metadata and promising them it will be deleted forever. Haven't we heard that before? Hush considers this a bug (possibly an attack) and not a feature.
