Why the BBC? It should go to archives like archive.org and publicly accessible "pirate" archives, so corporations like the BBC can't stick it in a vault and bury it.

Because the BBC might actually be interested in plugging holes in their own archive.

They can do that from archive.org

Your assuming that the archival format would be the same or that there's not anything else specific for their needs. Everybody thinks their snowflake is special, and definitely more special than anyone else's snowflake.

You're assuming that people can't get along. Is there some reason the BBC and archive.org can't work together to satisfy both of their wants and needs?

You sound like you've never worked with multiple vendors essentially needing the same thing but want different things.
