If a service provider detects illegal activity taking place on their services, I assume the correct action is to contact the relevant authorities and suspend the activity until it gets straightened out. Which seems to be what has happened here. I don't know exactly what efforts were made to work with Parler in advance but I do believe there have been some, and Parler has refused to take action on their own behalf.
