I absolutely see it as an owners concern because I am a member of the contract, No one party gets to decide what is and is not enforceable and Davids is doing the deciding,
In terms of others, his response is that all are individual contracts and not all will be settled the same way.
Of course, from Davids side, what he is proposing makes sense for him.
But why should he be the only one who gets to say what happens? Three people are involved, He can suggest, and so can the renter, and so can the owner. Like I said, I can cancel the reservation, tell the renter that I did, he can then tell Davids that the owner breached, and he is entitled to the refund.
Just as valid of a solution as what he has proposed, if we are simply changing terms of contracts at whim,
But, if you are saying the owner is not liable, so they can walk away with the 70%, then sure, he can do whatever he wants with the renters, As long as he involves the owner and renter in doing something, the owner and renters should have a say as well,
