They're trying to CYA for future ad campaigns, but they can't actually CTA their way.
No dice, Disney. The way this works is if you want to use the tweets shouted into the ether, you can, and if someone doesn't like it, they can sue you, and then the US (and probably international) law gets to figure out on your dime via the lawyers you will pay whether you misused the tweets.
... or, Disney does the not-lazy thing, gathers up the tweets, issues individual requests to use to every user who tweets into the hashtag, and only moves forward with the ones they get consent for.
... or, third option, Disney puts up their own website where users can submit tweets by URL, and submitting a tweet to that website (signed off by a user's Disney account) confirms the user is claiming they own copyright of the tweet and is authorizing Disney to use it.
But yeah, more than zero effort on Disney's part required.
The hilarious thing to me is that folks love that sort of attention and go out of their way to get a highlighted tweet - just DMing a few dozen folks with tweets you like to see if they're willing to have their random brain farts re-posted elsewhere will get you a lot of positive responses.
It's a good clarification of their intent, but I don't think it puts them on legal ground that's any less shaky. They'd still have to prove users had any intent at all of complying with their TOS in undertaking a public action that is only tangentially related to Disney's little slice of Twitter (hell, they'd have to prove users were aware of the TOS to even be compliant or not), and good luck with that if it ever came to court.
