These two, plus Matthew Barnett’s late Jan EA Forum post (which you linked), are the three examples I recall which look most like early visible public alarms from the rationality/EA community.
Other writing was less visible (e.g., on Twitter, Facebook, or Metaculus), less alarm-like (discussions of some aspect of what was happening rather than a call to attention), or later (like the putanumonit Seeing the Smoke post on Feb 27).
In the broader rationality/EA community there was also a Siderea post on Jan 30 and an 80K podcast on Feb 3 (along with a followup podcast on Feb 14).
