Privsec.dev is a libel slinger and an anonymity abuser on Reddit who is also Daniel Micay's equivalent of left hand. He is supportive of GrapheneOS and Micay's actions, and only went silent after Louis Rossmann exposed Micay.
GrapheneOS members, Micay and his friends like Wonderfall have attacked F-Droid in the name of security, only to push using Google Play Store that annihilates all privacy of people. Google Play Services gather every possible metric about your phone which includes sensor, location, IP address, telephone number, IMEI and so on every 7 minutes. Just to be fair, Apple does the same things and is far worse. This theme of evangelising Google products at the cost of bashing all other projects is a thumb rule for GrapheneOS community.
