I would say that that's an idea most have mulled over privately after finding out about it, but have either dismissed outright or have recalculated it into their risk factor.
Suresh will retire someday, just like all of us, so I see little harm in him lining up a few ducks for when that time comes. No different than being a board member with multiple companies when careers start to wind down.
For now, he seems determined, and has committed himself to proving, to the semi world, at least, that he didn't stall his career by leaving Global Foundry and that POET will be cutting edge tech and lead to the next big thing.
As shareholders, we are closer thsn ever to finding out if that's true or not.
