I believe this video discusses some of these, I’ll have to scroll through Mastodon to find more.
Edit examples:
I’m referring to Daniel Micay using the official account to fight other people.
Seems I’m not up to date, he supposedly “stepped down” from fighting others, https://www.reddit.com/r/PrivacyGuides/comments/13spm4d/dani...
I firmly recall within the past two years witnessing similar actions but I’ll have to keep searching

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.
Your example is not as unhinged as what I’m referring to.
