IBM boss joins Tim Cook in call for regulation after Facebook breach

More and more key players in the tech industry are voicing their concerns over the use of personal data following Facebook's massive Cambridge Analytica scandal. Executives from Apple Inc and IBM Corp have called for more oversight on how personal data is used following the consultancy firm's improper use of data, which affected more than 50 million Facebook users. Speaking at the three-day China Development Forum in Beijing, Apple chief Tim Cook said'well-crafted' regulation was required, while IBM Corp chief Virginia Rometty said users should have more agency over their own data. Executives from Apple Inc and IBM Corp have called for more oversight on how personal data is used following the Facebook Inc breach that saw roughly 50 million users' data misused by consultancy Cambridge Analytica. Facebook has come under intense scrutiny from users, lawmakers and investors following allegations from a whistleblower that it allowed British political consultancy Cambridge Analytica to improperly use data and build voter profiles that were later used to help elect U.S. President Donald Trump in 2016. U.S. lawmakers on Friday officially requested that Facebook's Mark Zuckerberg explain at a congressional hearing how user's data was released to the consultancy.
