“long term” is still indefinite and therefore unconscionable. “For at least 10 views” or “For at least 5 years” would work.

Another option would be Sony not entering unconscionable contracts with WB. They can because they’re gigantic and be laughed out of court if they tried to argue that their legal department didn’t spot the issue but their contract should have said that anythnig that gets licensed indeed gets licensed in perpetuity: That is, WB could say “don’t sell any new licenses any more”, but they couldn’t say “all licenses are now invalid, how you fulfil your contracts with your customers maybe buy boxsets”.
