Last week, a group of Apple employees wrote an open letter criticizing the company's hybrid work-from-home policy, which requires employees to be at the office three days a week starting May 23rd. Now, Apple has lost director of machine learning Ian Goodfellow over the policy, according to a tweet from The Verge's Zoë Schiffer. Goodfellow may have been the company's most cited machine learning expert, according to Schiffer. "I believe strongly that more flexibility would have been the best policy for my team," he wrote in a note to staff. A group of Apple staffers called "Apple Together" opposed to the RTO (return-to-office) strategy cited multiple arguments against it.
