I'm one of GrapheneOS's moderators and just saw this.
What I see here is someone who wants a feature, a feature that many people want, but it hasn't been added for reasons listed in the GrapheneOS issue tracker. No one was rude or anything there in that link you shared that I can see.

To say something like this is extremely out of line.
> Louis Rossmann’s video
What you fail to mention here is incredibly important context, but leaving that out conveniently supports the narrative that Daniel is crazy. Biggest fact there is that he had just been swatted multiple times. Louis commented on another harassment video and Daniel was understandably upset. By the way, the swatter had been in contact and even told GrapheneOS project members that they were a fan of the YouTuber who made the first video. So, attempted murder by some other person, a "friend" was supporting harassment content making him out to be "crazy" and comments on that video showing support for it, then, knowing that, Louis records a video of a private conversation in real time. The video itself was filled with lies and misrepresentations. Even the title was a lie because Rossmann continued to use GrapheneOS for long after that video was released.
Not to mention the fact that targeted updates aren't even possible on GrapheneOS considering how updates work and the infrastructure. Louis may not understand these things, but even though we and others have pointed this fact out multiple times, the video remains up. The video is clearly meant to do one thing: damage or destroy GrapheneOS.
