This is what TFA seems to say:
> Unlike the DMCA notice, where WBD used “video” to describe the content, the declaration to the court by Michael Bentkover classifies the infringing content as “summaries of unpublished, character, setting, and plots of a forthcoming series”.
Isn't that simply about spoiling people, or what's the "crime" here? The article also says "Copyright generally protects the expression of a work, not the underlying ideas or plot descriptions", so I'm still unsure what the actual issue is, besides the misuse of DMCA.
Most likely the culprit is someone on their staff that broke their NDA contract, but the DMCA is about stopping the proliferation of copyrighted material. They are misusing the DMCA because it has higher discovery/subpoena ability.
Can an NDA be used as justification for a DMCA? Has it happened before?
The crime is that we're living in a society where different laws apply to corporations than to people. If a corporation doesn't like you, you're toast, no matter whether you're wrong or right.
There are enough laws that they'll find something to nail you on.
Under the DMCA, you can claim copyright over damn near anything and force a provider to take it down. If there is any ambiguity as to whether you are the owner of the allegedly copyrighted material, like for example legitimate fair use, they still are required to take it down—unless the alleged violator files a DMCA counterclaim in which they must supply their legal name and address to the original claimant. This has been used to silence, or deanonymize, people who post unpleasant things about a powerful person or organization.
