You can assume that a high-profile game developer in a business partnership with Google is evil and got up to some sort of large scale malfeasance with their gmail account (why??? for what purpose? why would you risk a business deal to do this? what's the upside?) and then Google decided to ban them but not expose them for their misconduct. Or you can go "huh it sure seems like something bad happened to this person and he's not getting an explanation for it."
