You are the person paying the seeds ( people will do the work of storing and seeding the files). If your computer or your internet access are blocked or some ( but not all) seeds are blocked by ( censorship actors - you already know who) , hopefully, the rest of the seeds still are able to seed , so other can leech to view/ watch the file/ video on nostr clients. You pay the seeds the amount to pitch to them, if they agree to do the work.
