As the internet is a highly ambiguous place and people can pretend to be whoever they'd like to be (or not being people after all but bots), did you ever consider that someone else is after you, while they're framing it on another open source community? Do you really have any proof that Murena leadership authorized these actions? I am a little irritated that you're so bold on these attributions.
In game theory, it would be much more adequate to assume that these attacks were orchestrated by a government entity which is annoyed that GrapheneOS is making it hard for them to spy on people.
Call me naïve, but hopefully the current POTUS will stop those unlawful practices.
