When we get the full story it's usually less black and white. Quick skim over the thread and it sounds like they let an ex-employee have access to one of their accounts and he committed multiple violations? Was he spamming? Was he uploading malicious content to the store?
Also, don't build on others platforms if you want to control your destiny. You can't have it both ways.
Our company account is assumed to be "associated" with wrongdoing of my former employee. This is the black side.
In the future, fully control the accounts yourself or don't build in someones walled garden and then complain when they ask you to leave.
It's a warning that if your livelihood or something is really important to you, you should not build it inside google or apples walled garden. Or if you do, know that for any reason they choose they can kick you off. Unfair as that is.
Welcome to capitalism. Go host your own stuff if you don't like their rules.
