SoFi hasn't locked down the terms of the job, according to the tipsters, and a decision is expected sometime in the "coming days." Noto might decide to stay aboard, and there haven't been public signs that he was less than thrilled at Twitter -- he'd certainly be taking a less glamorous position. The COO hasn't commented on the rumor.

The lending firm's previous CEO, left in September after numerous reports of sexual harassment.

If Noto did leave, it could throw a wrench into Twitter's livestreaming efforts. He didn't have a perfect track record (he secured an NFL game deal in 2016 only to lose it to Amazon the next year), but whoever replaced him would have to take time getting up to speed. And that's assuming the replacement is as supportive of the concept as Noto was. If not, you could see Twitter change direction and cast uncertainty over its hopes of turning a profit.
