What are their motives could it be that they are just anti Bitcoin or attacking Bitcoin because it is a competitor that will soon push them out of business.
How do you imagine Bitcoin putting banks out of the business? It has 250k transactions per day which is close to its limit, and the world has hundreds of millions, or maybe even billions of transactions per day. Even with Lightning Network the capacity is not enough to open channels for enough users and the fees would skyrocket.
Banks generally don't care about Bitcoin, payment companies either. Most Bitcoin haters are just people who like to feel that they are smarter than others, and they think that this is what's happening when they are warning others about Bitcoin's "imminent collapse".
