For me it sounds quite alarming that the source code for whatever reason can't be verified completely (!! #wtf)
Also alarming is why Vitor refuses to provide an #F-Droid version with #Orbot -outsourced #Tor option. This is not a big deal imho.
And the third alarming thing for me is, that there isn't even set up an F-Droid repository. Instead they recommend #Goolag PlayStore.
What an utter mess!! So I have to consider #Amethyst dead and #compromised.
How can I trust my privacy to such a fishy project?
Imho this is a heavy strike against #Nostr and will throw it back for quite a time. Disgusting.
