Technically, Toshiba didnít pay for exclusivity either as the money was buried in marketing budgets of select films. You canít have it both ways, if Disney was given replication subsidies then they were paid off, plain and simple.
Disney did not sign a contract for Blu-ray exclusivity: The agreement with Sony was not one to prevent them from releasing on another format, only one to incentivise BD production. That's very different than Paramount's exclusivity deal with Toshiba which, by contract, instructed them to hault Blu-ray production.
Agreed that the financial incentives were similar in both cases.
