People can accidentally be spreading attacks with loaded/presumptuous statements even when their intentions are pure. Unfortunately, pure intentions can still cause harm that needs to be countered.

Take your reply as an example, the GrapheneOS accounts are managed by multiple people, so the fixation on one specific project member may not even be accurate to the discussion. Having ones character attacked is immensely harmful on its own, but being attacked for something one may not even be doing is also immensely harmful.

The unfortunate reality is that people tend to believe the first thing they read, and without something countering it, will roll with it, intentionally or otherwise. So countering misinfo efficiently and quickly is vital.
