An anonymous reader quotes a report from The Guardian:On Monday, ARM co-founder Hermann Hauser penned an open letter to the UK's Prime Minister Boris Johnson in which he says that he is "extremely concerned" about the deal and how it will impact jobs in the country, Arm's business model and the future of the country's economic sovereignty independent of the U.S. and U.S. interests.A spokesperson for Arm said: "Communication sessions have been ongoing with employees at a global, regional and departmental level since the deal was made public. Together, [Arm CEO] Simon Segars and [Nvidia CEO] Jensen Huang held multiple interactive communications sessions with Arm employees, providing them with the highest levels of transparency within the legal constraints of the situation. It was also clearly communicated that the regulatory process does not have a specific timetable and employees will be kept informed as we get more information relating to the initial estimate of 18 months."
