Mr. Singer, the spokesman for Mr. Rubin, said the executive “is known to be transparent and forthcoming with his feedback.” He said Mr. Rubin never called anyone incompetent.
Mr. Rubin, 55, who met his wife at Google, also dated other women at the company while married, said four people who worked with him. In 2011, he had a consensual relationship with a woman on the Android team who did not report to him, they said. They said Google’s human resources department was not informed, despite rules requiring disclosure when managers date someone who directly or indirectly reports to them.
In a civil suit filed this month by Mr. Rubin’s ex-wife, Rie Rubin, she claimed he had multiple “ownership relationships” with other women during their marriage, paying hundreds of thousands of dollars to them. The couple were divorced in August.
The suit included a screenshot of an August 2015 email Mr. Rubin sent to one woman. “You will be happy being taken care of,” he wrote. “Being owned is kinda like you are my property, and I can loan you to other people.”
In 2011, Mr. Rubin was appointed a Google senior vice president and started receiving about $20 million a year in salary, bonus and stock-based compensation, said two former Google executives with knowledge of the terms. In 2012, Google also lent Mr. Rubin $14 million to buy a beach estate in Japan. The loan was offered at below 1 percent interest, said people briefed on the transaction.
When Google combined management of Android with its Chrome division in 2013, Mr. Rubin lost a power struggle to Sundar Pichai, Google’s current chief executive.
He remained highly valued. That year, Google offered Mr. Rubin a one-time bonus of $40 million in stock and an additional $72 million of stock over the next two years, said two people with knowledge of the terms.
