What that means is that if you tweet something with the hashtag and they like it, they can use it without contacting you. Which means that you may be part of a promotion somewhere and not even know it. It would be nice if they contacted you so at least you would know, and they may do that. But they absolutely don’t have to since by using that hashtag you are agreeing for them to use it.

Now the problem becomes what if you don’t know about this? What if you don’t follow Disney+ but just like Star Wars and use the hashtag anyway? How would you even know any of this was going on? Well the answer is you wouldn’t. And they could still use whatever you posted if they wanted to.
