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.
Basically "if you wanted it you could have asked for it, if you didn't then that is a problem".
>...any legal entity or business, such entity or business (collectively, “You” or “Your”)
And I might have a call with any other zoom user, too, potentially, maybe. So really they are doing me a service by using my content all over the place — who knows, it might benefit me at some point!
