&gt;a photo&#x2F;comment the creator willingly released to the public and attached to the brand logically allows for re-sharing that content to me, especially by the entity explicitly mentioned.<p>I don&#x27;t see why you think that at all.  Re-tweeting, sure, but that&#x27;s because it&#x27;s an expected result of putting something on twitter, with or without tags or even text.<p>Sending someone a picture on twitter in no way implies I am giving it to them to do whatever they want, in the absence of external context.<p>Or in other words: The tweet as a whole is released to the public of twitter.  There&#x27;s no license to derive or take elsewhere.<p>Sending it directly in the mail doesn&#x27;t let them use it to advertise either.
