Here is Meta's response:

Meta denies that they violated the Wiretap Act but offers no evidence of consent. (They try, but it is a laughable attempt.) Meta is also arguing the documents are not relevant. Meta claims the VPN app intercepting communications with other companies that sell online ad services, e.g., Snap, was not anti-competitive. It was just "market research".
Why is Meta so afraid to produce documents about "market research".
Meta does _not_ deny that they intercepted communications. From the attention this is getting on HN, MalwareBytes, etc. it seems clear no one using the VPN app would have expected Meta was conducting this interception. It is difficult to imagine how anyone could have consented to interception they would never have expected.

Apparently Facebook was using a "really old" version of squid.
