Can a company market a submarine but then define a submarine as a lamp in their ToS and you’d just be out of luck?
No, because a ToS can’t cure an obviously false advertisement, but when looking at what a reasonable consumer would take away from the advertisement, you can see the ToS is clarifying what a reasonable person would already assume – namely that MrBeast, before sending 42 junior high students to fight to the death in a chocolate factory, spending 45 seconds in order to rave about how much he loves to put Hello Kitty-branded capsaicin under his foreskin isn’t something that YouTube Premium is going to get rid of.
