Clearly, they did not. California is an all party consent state. There is no reason to build a VPN snooping system if you have consent of all parties; Snap Inc could've just straight up given them usage information and/or direct access to monitor behavioral data and read conversations in the app if everyone consented. That would have been much cheaper and simpler if everyone consents. The entire point of building this system is that Snap Inc, at a minimum, did NOT consent. Additionally, I find it very likely that the other participants in conversations on the platform who were monitored did not consent either. The user who installed the app may have consented, but that is not good enough in California. ALL parties must consent.
