Boston Tech Watch: Huawei, Care.com, Cambridge Blockchain & PayPal

—MIT cut ties with Chinese technology giant Huawei and ZTE “due to federal investigations regarding violations of sanction restrictions,” the university’s head of research wrote in a memo to her colleagues this week. “It is designed to enable MIT to engage with the world effectively, with responsible management of risks and in keeping with the values of our community,” Vice President of Research Maria Zuber and Associate Provost Richard Lester wrote in the letter. —An investor in Waltham, MA-based Care.com (NYSE: CRCM ) has filed a class action lawsuit against the childcare marketplace, accusing the company of making false and misleading claims about the screening of care providers against databases and criminal records. —Payments giant PayPal (NASDAQ: PYPL ) gave digital identity startup Cambridge Blockchain a boost by joining its Series A funding round with an investment of an undisclosed size. —Boston Dynamics, a division of Japan-based technology conglomerate SoftBank, has acquired Menlo Park, CA-based Kinema Systems in a deal that will expand the robotics company’s reach into industrial logistics and bolster its 3D-vision capabilities.
