The GOS (GrapheneOS) lead had responded to criticisms like yours that he gladly retreats inside his tech role if others would take it upon them to refute the claims from rivals. So if you are that balanced, normal person, you could take that work out of his hands. Or help fund a full time PR person.
«In 2018, matters between Micay and Donaldson came to a head over Donaldson’s desire to pursue business deals with criminal organizations, and his attempts to compromise the security of CopperheadOS, including by proposing license enforcement and remote updating systems that would allow third-parties to have access to users’ phones. As part of this process, Donaldson began to demand that Micay provide Donaldson with the “signing keys” - i.e. the credentials required to verify the authenticity of releases of CopperheadOS. Donaldson advised that, in order to secure certain new business, potential customers required access to the Keys.»
Micay is rightfully paranoia, just having a GOS phone makes some government agencies quite mad. There are many ways a project like GOS could die, disinformation could certainly kill it. Other projects don't help the case if they throw mud at it. Rather, they should focus on their real technical shortcomings, but such articles aren't written somehow. https://eylenburg.github.io/android_comparison.htm
