Whoa ... I'm sure you've thought about changing the urls of your assets and update you code before publishing it again, then why haven't you done this ?
Probably because they are trying to open up an account for them, rather than Al-Jazeera stealing their code. Changing the URLs would probably make them angry/upset and not thinking about making business with Storytelling
Probably moot; I rather doubt that sending them a DMCA takedown notice will make them too interested in doing business with them
I've thought about this but that does not move the discourse forward at all and it hurts the readers of the story. We're not here to make anyone upset, least of all readers of the story. We'd just like Al-Jazeera to not leech off our bandwidth bill. And if they want to come on board, that's awesome. Still welcome.
