"Balwani's counsel and the prosecution also differed on whether Balwani or Holmes were really leading the conspiracy."
The Wikipedia pages are pretty telling though:

"In the 1990s, Balwani worked for Lotus Software and Microsoft. During Balwani's tenure at Microsoft he worked in sales. He claims to have written thousands of lines of code; however, independent investigations could not verify this, and numerous Microsoft managers who were asked about him could not remember him."
"In July 2000, Balwani sold his shares in Commerce One, netting nearly $40 million shortly before the company went out of business, just before the dot com bubble burst."
"Holmes met Balwani in 2002 during a trip to Beijing as part of Stanford University's Mandarin program. Holmes was 18 at the time, and had just graduated from high school; Balwani was 19 years older than she was and was married to another woman at the time."
"On November 29, 2021, Holmes testified that she had been raped while she was a student at Stanford and that she sought solace from Balwani in the aftermath of the incident. She also said Balwani was very controlling during their romantic relationship, which lasted more than a decade, and at times he berated and sexually abused her. In her testimony, she stated he also wanted to "kill the person" she was and create a "new Elizabeth"."
