@sally There is no law making it illegal to claim that only arbitration is allowed - so of course companies would claim that only arbitration is allowed.

There is contract law, but that's only relevant when the contract is fair (although you have to require something incredible for a contract to be deemed unfair), the party has understood it and has signed it.

Is this case there was no contract - there was only a long past agreement that x party would try out "disney+" at no charge and proceed to pay monthly rent for continued access to the videos if x party wanted to.
