If he never claimed the credential then I would be more than willing to judge him on his accomplishments.

Lying about the credential wipes out his accomplishments, at least as a C level steward of shareholder value and employee well being. He is demonstrably unethical and I would not feel safe working for him. I would never give him my money, because while he may be able to demonstrate past success, that does not imply that he won't fabricate a ponzi scheme in the future to prop up stock prices and options.
