Unlikely, based on his public comments.
Here is David Schwartz on the pre-Stellar Jed/Jesse situation:
This is David Schwartz, JoelKatz on the Bitcoin forums. I first became involved in what became Ripple Labs when Jed McCaleb hired me to investigate if a distributed agreement protocol could solve the double spend problem without a central authority. Jed and I met Jesse Powell at a burrito shop in Berkeley and convinced him to become the first investor.
Chris Larsen co-founded the company with Jed, taking on the operating role of CEO. With Chris at the helm, Ripple Labs has grown to a team of more than 50 people, pursuing a shared vision to make the Ripple protocol an open, decentralized, payment system by building utility and liquidity. Today, I'm Chief Cryptographer at Ripple Labs and a member of the Board of Directors.
We knew we would face a number of challenges, from the technical to the regulatory, but nobody could have expected the destructive behavior we've seen these past few days. Jesse's assertion that Chris was and is unwilling to give back his founders' stake to Ripple Labs is completely untrue. Arthur posted on the issue yesterday. I trust that the community has the judgment to see who is building and who is scorching the Earth.
As he is an active forum member on bitcointalk.org---I am hoping that he may answer for himself.
Are you able to cite any sources?
Am I reading correctly that 'Stellar Doge' is the sole source of the rumor?
