How much of this is on Trump is to be decided by the people who are going to judge him, if ever. Meanwhile everyone is entitled to have opinions on it and advocate these opinions.
However, the reality is that we have an overwhelming evidence of dangerous people doing something malicious and getting organised on some platforms, including but not limited to FB. Therefore people in immediate danger and the people who are directly assaulted or feel threatened demand actions to be taken. It's either let it run and turn into civil war or break the circuit before it goes any further.
Let's not pretend that this is about intellectual discussions, it's literally about taking power with force. People actually died and they did not die when looting or anything like that but when they were faced with counter force when they attempt to achieve their objective.
You either let it run its course and have a memorial day afterwards where you distribute medals to the best killers who survived or intervene in stop the conflict. Some people simply don't believe in the wonders of the war or don't think that there's a good enough cause for having one and currently it happens that these people are in control of the systems.
