It never ceases to amaze me how companies choose the worst software!
> You give 8×8 (and those we work with) a worldwide license to use, host, store, reproduce, modify, create derivative works..., 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.
IANAL, but it seems like that would include training on your data as long as the model was used as part of their service.
Everyone who operates a video conferencing service will have some sort of clause like this in their ToS. Zoom is being more explicit, which is generally a good thing. If Jitsi wanted to be equally explicit, they could add something clarifying that this does not include training AI models.
To me (a former corporate lawyer) the "for You" qualifier would limit their ability to use content to train an AI for use by anyone other than "You". Is there an argument? Yes. But by that argument, they would also be allowed to "publicly perform" my videoconf calls for some flimsy reasons that don't directly benefit me.
