Oracle may be engaged in illegal fraudulent attempts to extort money
Section 380 of the Criminal code of Canada makes it a felony (serious offence) to obtain money or anything of value from others by deceit, and even the attempt to do so is a crime. U.K. law is probably similar. The crime of false pretenses may also be relevant here. Oracle's managers obviously think it is not bound by ordinary laws by trying the gambit described here. Their behaviour is shameful. The U.K. police and prosecutors should investigate and take appropriate action against the company and/or its involved managers.
