Good clarification, but it's still, I think, somewhat unclear whether there's any kind of enforceable contract they could claim there. Here's what that court conversation would likely look like in civil court:
Disney: "As per our first tweet, when the user replied to use with #MayThe4th, they were giving consent to use their tweet in our ad campaign."
Judge: "Were you aware of the first tweet?"
Plaintiff: "No, your honor. I posted my tweet in reply to the Disney+ account because I saw my friends doing it. The thread was ten thousand messages long; I didn't read the whole thing."
Not exactly a slam-dunk case for the plaintiff here, but I'd have to see precedent to show how a TOS that cannot practically be read is enforceable.
Disney's tweets are better understood as a "heads up" to people, than creating any sort of right that Disney will actually try to defend.
There is zero chance Disney will try to argue about this content. If someone complains at all, Disney will just take their tweet down and replace it with another one. There are plenty more fans out there who would be psyched to see their tweet being promoted.
