It is, though I suspect there may be some expectation that voice-to-text transcription only occurs when one clicks a button to make it so.

I just like how everyone is up in arms over the use of your meetings for AI training specifically, when the ToS clearly says all "Customer Content/Customer Input" AKA your words, text, voice, face, etc can be used for "Product and Services Development" which could as easily be a facial recognition database, a corporate espionage service, a direct competitor to whatever company you work for, or literally anything else before it's an AI lol.
