I wonder if this is another marketing gimmick similar to end to end encryption controversy they got into. I hope by ultrasonic they just mean beyond hearing and not really that watermark lives exclusively in ultrasonic frequency range.
Do they also talk about the process for identifying the participant who leaked the content based on the leaked recording? Do they need to retain the original copy of the recording to be able to extract the watermark?
