We already know the likely answer to this. They didn't make it terribly evident to Google Voice (Former Grand Central) users that their data was being utilized to train their transcription models for visual voicemail and the like. Google has long since strayed from their do not evil model. People would be wise to de-Googlify their digital presence as best they can. The new Gmail ads are atrocious too, IMHO. Peppering ads that "appear" as emails into my Gmail feed seems over the top. I'd rather pay $6/mo, and do, for a single-user Microsoft 365 tenant, which nets me 1TB of cloud storage, in addition to 50 GB of email. I trust Microsoft more than I do Google at this stage.
