It's the inevitable result of the Fair, Isaac Company deciding to sell access to credit scores to the general public: some marketing dude at one of the banks thought, "Wouldn't it be a great idea if we could use 'free' access to FICO scores as a differentiator for our CCs?" And, because most humans play follow the leader, soon enough, other banks were paying FICO a license to present FICO scores to their card holders.
