Apple spends a lot of money to keep its secrets. Paying $95 million to avoid letting people snoop in exactly how Apple systems work is a bargain, and I don't even think they're using audio for ad targeting.
Eh I don't think that is what happened here. If other companies want to know how Apple did things 5 years ago, they can just hire some ex-Apple employees. I think someone could build a competitive system with current technology for something in the ballpark of $95 million lol.
