From a potential culpability or liability perspective, the question of targeted advertising is irrelevant. Intercepting private communications without consent, absent an applicable exception, is still against the law, e.g., the Wiretap Act and/or the California Invasion of Proivacy Act, ads or no ads. Targeted ads would not be used as evidence that private communications have been intercepted.

Many years ago, Google was sued for wiretapping and lost. See Joffe v Google

More recently Apple was sued for eavesdropping without consent. They just settled for $95 million. See Lopez v Apple
