It actually astounds me this is getting any number of upvotes on HN at all - it's so obviously LLM written (or at minimum heavily edited) that it's written in markdown on a platform that doesn't appear to support markdown.

It literally hits almost every major identifier of AI writing. You could probably get similar output yourself with a prompt along the lines of "Write a blog post analyzing the GrapheneOS infrastructure based on public information such as GitHub repositories. Focus on contrasting the security of the phone OS with the unnecessary attack surface and similar decisions of the infrastructure repos."
