You never mentioned that the friend was ingesting this in any way other than taking a physical disc from you
They ingest the content by watching it. They do not ingest the DVD, nor the torrent file.
If your friend has your DVD, you can’t watch it while they have it in their possession.
I’ve already “ingested” the content, and paid the creator for it, like they asked. But my friend did not pay the creator, yet has “gained something from their work without compensating them”.
