No, but an app like Signal claiming to care about privacy should at least make an effort to be on the largest open source appstore. The fact they don’t, despite very loud complaints from the community, makes me question their commitment to privacy and security.
Signal devs accuse f-droid for not being secure, but do not offer any convincing arguments to back it up. Just saying it doesn’t make it so.
F-Droid works. I have 20+ apps installed on my phone from F-Droid. I am not going to go back to installing apks from website or Google Play just so that I can use Signal.
