This. Don't make the same mistake as Ripple did when they let rogue founder Jed McCaleb leave with his share of the premine. Ripple price has never recovered. They had to bring the matter to court and have a long and messy legal battle to reach an agreement restraining his sale rate. Even today the ongoing selling by Jed is still a major hindrance to price appreciation.

Ripple let McCaleb run with his cut of the premine because they thought it would be messy to fork and have all exchanges switch to a new asset. They were also concerned that Jed would have a legal edge against them by claiming he was wronged.

In the case of Synereo it is easy to avoid the situation. Just create a new Omni asset and have all exchanges switch asset just like Tau/Agoras did when they got hacked. Greg can still enjoy his worthless and meaningless tokens after that so he won't have much leverage claiming he was wronged. He still got his share of the profits of the product he failed to deliver.

Either way don't let Greg enjoy a founder cut of whatever Synereo does after his departure. None of his work is usable in the end. His net contribution is negative: a huge waste of time and investor confidence.

Synereo has to make a move here and distance itself asap from its rogue founder if it wishes to retain its credibility.
