The headline is in theory true, in practice not.

"In their ruling, the panel of three appellate judges found that Google and its co-defendants hadn’t violated the Wiretap Act because they were a “party” to the communications rather than a third-party eavesdropper—"

This is consistent with the ruling, but buries the part that is important for most folks: http://www2.ca3.uscourts.gov/opinarch/134300p.pdf (page 35).

Because they were the intended party of the communication, they will never be liable under the wiretap act. Ever.

So yeah, if some third party you aren't communicating with grabs your cookies (cough cough), that may be an issue.

Otherwise, no.
