Not hard to do some Google searches to find lots of examples where people were banned by Google without reason or explanation. Sure, a reason might exist, but if it's impossible to get anyone to tell you what it is, then how can you tell? In at least one high profile case a Google employee's spouse was banned and it was still impossible to get an explanation or reversal!

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."
