Executive tensions led to Google Cloud chief departure, report says
"One source of tension with other leaders within Google was Ms. Greene’s efforts to piggyback on other parts of the company’s business. She would often seek to make other Google business partnerships and advertising deals contingent on a deal of some kind with the company’s cloud unit, according to people briefed on the talks, a strategy she has tried with companies including Salesforce. That sometimes frustrated other department chiefs who felt her unit didn't have the clout to justify those kinds of requests, these people said.”
In 2016, Greene reportedly proposed a co-marketing relationship with DeepMind, Alphabet's artificial intelligence company, that would enable Google Cloud to market itself as “Powered by DeepMind”
