Here Facebook is not targeting anti-lockdown accounts here. It's just the shortcut used by the article's title but the targeting is different. They are targeting accounts that are coordinating themselves to spread misinformation and incite violence.
That's all well and good, save for the fact that "violence" has become a much squishier term lately. Particularly, though not exclusively, on the the left there's an increasing tendency to classify unpopular or ugly speech (as opposed to actions) as a form of violence. It's not hard to see where this goes.
