If its an app they wanted kept under wraps, it will make the while Hegseth situation seem a lot more benign.
I use Molly Messenger on a secondary phone that doesn't have a SIM, its a fork of Signal with a few differences related to encryption at rest. It still works with normal signal users just fine, on the other end you can't tell I have a different client. If the government has a similarly forked version you could likely still accidentally invite the wrong user in from their normal Signal app and they wouldn't know you're on a forked version with government archiving features.
I find the Signal devs' attitude so frustrating; they deliberately disable the ability to use Signal in secondary device mode for phone-sized-devices, because they know the Correct Way To Use Signal™ is to only use it on one phone-sized-device.
