I don't generally condone punishing employees for what their employers do, but this is a company whose whole business centers on unauthorized control of private resources. It's not at all a stretch to suppose that they exert such control over their own employees' accounts, or would consider doing so, making those accounts effectively proxies for the company. It's unfortunate that the employees are caught in the middle, but their inconvenience (this is social media not bank accounts) is outweighed by other concerns.
