Sorry, slow okie. Dewey Keith Gabriel had no incentive to maintain ties with IHSI.
He was/is a General Contractor. As such, he had few if any employees, and minimal if any equipment.
A General Contractor is basically just a guy's company Name, reputation, and a network of sub-contractors that can be contracted with on an as-needed basis. Plumbers, electricians, carpenters and such.
He agreed to stay with the new Cresent as an advisor for a year, I think.
In return, IHSI/TCA paid him $500K+ for the use of the company name and his (brief) services. Turns out they never used his services, as they could not commit to any new projects.
DKG did what any sane businessman would do. Took the money and walked away.
Opened up shop elsewhere and took his reputation, name (slightly changed but recognizable), reputation, and network of sub-contractors with him.
He has no reason to give any revenues to IHSI.
None.
