It's a communication issue at the core, and always doubling down is not making it any better.
It portrays the whole project as being unreliable.
So no, it isn't as "simple" as the issue being only the literal content of that comment. The context matters.
If this person has indeed mental issues, to publicly expose it in a degrading light does not help him, or anyone else really.
If he doesn't have mental issues then all this discussion is unjustly defaming a person and damaging perception around mental issues.
Either way this discussion is bad.
You are the one portraying the project as unreliable. I only judge GrapheneOS by the actual output being delivered, the code and and the binary that is. And if you go down the route of validating the output based on his behaviour then i would flip it on you. I would much rather use an OS developed by a paranoid guy who thinks everyone hunts them. I'd bet it's more secure.
But this is silly-talk. What matters is the deliverable. Has the project given any evidence of being unreliable or not teustworthy?
The video is harassment content, plain and simple. It's filled with disinformation and he lied about not using GrapheneOS moving forward. The developer was swatted multiple times, then when upset with Rossmann he tried to talk to him about his support for harassment content (the swatter was a fan), and instead of being a decent human being, Rossmann made a video of it while it was happening.
Many people enjoy participating in harassment towards an open source developer when they have a disagreement with the project such as our requirements for accepting a pull request for automatic call recording. We've said we won't accept it without showing that it's active so that people are aware calls are being recorded when it's enabled. That's more than enough for some people to participate in harassment.
Hacker News shouldn't be permitting it over and over again.
