  177. F-Droid: how is it weakening the Android security model? | Wonder's Lab - Commented by a F-Droid dev: "The thing that preluded them doing this was the fact that they made some incorrect statements about F-Droid on Twitter, when I corrected them said F-Droid is "ran by a known malicious actor" and when I called them out on spreading FUD they tried to sue me. And I don't let myself be shut down by someone who threatens to sue me when I call out their nonsense. So now they completely hate F-Droid because one person who happens to contribute == F-Droid team in their head. So shrugs I'm sorry for upsetting the Graphene devs by calling lies out in public".
