I cant imagine many people are backing up movies/tv shows, certainly not ones readily available should a recovery be needed. I can understand more obscure shows but backing up something like The Odyssey would be a colossal waste of storage and money.
For a while Google Workspace didn't enforce the 5TB per user limit and eventually I had 50TB of suspiciously named backups (for real, you should see my DVD collection). Nothing came out of it except for the enforcement and the pain of moving everything elsewhere again.
I can assure you it is readily available online and always will be. And now that we've had confirmation you basically own nothing then it'll be more prominent than ever.
(But yes - regardless of what it is, encrypt it)
