from “4. Your Content” (emphasis mine)

You give 8×8 (and those we work with) a worldwide license to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes we make so that Your content works better with the Service), communicate, publish, publicly perform, publicly display, and distribute such content solely for the limited purpose of operating and enabling the Service to work as intended for You and for no other purposes.

Despite the good intention from the company, this sounds like lawyer-speak that legally protect them if they decided to use your content to train ML model. IANAL though.

But it’s not the same as Zooms policy. I agree. I stand corrected and edited my original comment.

On the thread about this on HN someone posted a link stating Jitsi has the same policy as Zoom regarding this matter. It’s equally bad.

Edit: I stand corrected, apologies. It’s not the same policy as zoom.
