Update: Zoom has clarified its position in a new blog post which makes it clear that AI features are, in fact, opt-in.

Zoom’s terms of service now allow meeting content to be used to train AI, without opt-out:

What raises alarm is the explicit mention of the company's right to use this data for machine learning and artificial intelligence, including training and tuning of algorithms and models. This effectively allows Zoom to train its AI on customer content without providing an opt-out option, a decision that is likely to spark significant debate about user privacy and consent.

Google Meet also appears to train AI on meeting content. I would guess that virtually every newsroom in the country uses a videoconferencing solution that allows the content of customer calls to be used to train AI.

This blanket approval also means that this customer data may be available within a model somewhere (albeit not publicly) to be perused, including sensitive information about ongoing investigations and reporting on abuse of power.

Platforms like Wire may be more secure. At any rate, anyone discussing sensitive information may wish to find a solution beyond the usual suspects.
