Patrick Moorhead, an analyst with Moor Insights & Strategy, said he wouldn't be surprised if Rubin didn't care for having to suddenly report to Pichai. He also noted that Google might also be scaling back on the robotics acquisitions, leaving Rubin in a less powerful position.
"After the reorganization, there could have been some disagreement over reporting," he added. "Regardless of the trigger point, the shakeup [at Google] continues."
Despite the fact that Rubin had ridden Android to a high position of popularity and power, Moorhead did not see Rubin's departure as a huge loss for Google.
"He had been off working science projects, not really in the mainstream business anymore," he explained. "Additionally, he isn't the most public figure either, so it's not like they lost the face of Google."
