Any examples?

Here's an example of what they're responding to with inaccurate personal attacks:

GrapheneOS posts factual information debunking inaccurate claims from groups attacking it. Some of those groups react to their misleading claims being addressed with personal attacks. Threads about GrapheneOS on Hacker News usually have multiple posts with personal attacks towards our team from people influenced by those groups.

> GrapheneOS is security before anything else.

GrapheneOS is a privacy project highly focused on usability and compatibility. Privacy depends on security so it has to put a lot of work into security too and it has always been a major focus, but it's a misconception that it's all about security.

> This means they strongly advice against using other software many in their core audience are predisposed to like: Firefox, Signal, plugins for browsers, F-Droid, ect.

GrapheneOS doesn't recommend against Signal but rather it's the main recommendation for end-to-end encrypted chat from the project including via the Molly fork of Signal.

> The explanations are usually quite... blunt, and they're not exactly open for discussion (which makes sense, from a pure security perspective, those apps are indefensible).

This isn't true. GrapheneOS provides nuanced information with detailed explanations for these topics.
