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.

Yeah but if you don't put that info in the original tweet, that's really a stretch. At least put 1/2 and 2/2.
