Are damages automatically at fault of the guest?

[Lior20]

A bed frame broke when I sat on a bed in a place I was staying. The host requested the cost of bed frame replacement, arguing the bed was relatively new. After two attempts to argue that it's not my fault that a bed frame broke from simply sitting on a bed, Airbnb resolution failed to address my concerns and simply shrugged me off, providing zero explanation why I'm being charged except for saying "everything that happens during my stay is my fault". Fortunately the charge wasn't that high, but it shuttered my trust in Airbnb at a possibility of a future attempt at requesting large sums of me happens and it's not my fault.
