What do you mean by "false sense of security"? Signal's cryptography is pretty solid. It's one of the only messengers with such a lack of metadata leakage; if you combine it with Tor you can add enough noise to the network-layer metadata to be more private than almost any alternative.
Don't get me wrong, [I dislike it on the grounds of being a closed platform](https://seirdy.one/2021/01/27/whatsapp-and-the-domestication-of-users.html), but few alternatives exist that support both offline messaging and have such little metadata leakage. I'm willing to hear suggested alternatives that do not bake a "cryptographically-secure, decentralized pyramid scheme" (cryptocurrency) into the protocol. I'm not aware of any such alternative at the moment.
