Doesn't your second paragraph run against the grain of your first? If streaming services like Netflix are harmful then we should avoid using them. Thus it should not be important for our freedom-preserving computers to be able to access Netflix.
Now, if you want to do an in-depth study of film and television material as a whole, you're actually better off avoiding Netflix and making use of archives such as public libraries, university libraries, and the Internet Archive.
