That's a fairly large ethical gap between those two Gray Hat definitions.
As a, fairly well read, outsider, Black Hat, to me, always implied actualy damage, financial or otherwise.
Gray Hats, on the other hand, still might break in and exploit vulnerabilities, but made certain not to cause any damage.
I suppose this partitioned people based on primary motivation. Black Hat's were in it for personal gain or evil, White Hat's for protection, and Gray Hat's for intellectual pursuit. Much easier to categorize and rationalize the romanticism associated with the culture when your "team" is the Gray Hat's.
