Molly advertises itself as a “hardened version of Signal,” & its FOSS variant is the same without proprietary dependencies. TwinHelix’s FOSS Signal fork goes further, adding OSM support instead of GMaps. Are these forks trustworthy, & are they worth using for added security compared to mainline?
Not really, since Signal servers are still proprietaty and centralized. But this mostly isn’t a privacy issue, it’s a different kind of issue.
