Today June 23, 2021, the court hearing took place and we got to hear Britney speak. Recording was illegal but it was legal to hear the audio. Obviously, the audio has leaked in many places so you can search it on your own however here is the full transcript from Variety. Please be aware though that Variety has missed some parts from the hearing like the "AA meetings".
Now that Britney is vocal, more celebrities will speak out one after another but as fans we can help by continuing with spreading awareness, call and writing to Congress and California court system, calling California legislators, flooding media outlets with fan testimonies, etc.
