We’ve updated our terms of service (in section 10.4) to further confirm that we will not use audio, video, or chat customer content to train our artificial intelligence models without your consent. https://blog.zoom.us/zooms-term-service-ai/
I do not think that blog posts have any legal value whatsoever. The current terms of service are too risky for most companies who would otherwise have loved to continue to be users of your product.
