We've talked plenty of times in the past about instances in which publishers of content, typically movies, get copyright takedowns performed on trailers. These takedowns are, frankly, never a great idea, but they are particularly stupid when companies like Marvel, Disney, and Warner Bros. takedown trailers, otherwise known as advertisements, and then release an identical or nearly identical trailer days later. What in the actual hell is the point of that? Killing off your own word of mouth and free advertising for your film?

Now, Sony just went through this experience itself, having attempted to DMCA to death a leaked and, importantly, unfinished trailer for Spider-Man: No Way Home.
