People here assume it's developers' fault. This is just a speculation (at least, OP only mentioned it as a possibility). It could be, for example, that developers previously used one of their client's accounts (to deploy an app), which was later banned (could be even for a different app they have no connection to). Some information is missing here (developers' side of story?)

Nothing is missing, from Google's perspective, the 3rd party took care of everything, and the investor (the writer in this case) was just a name in the account.
