One of the issues was that "she could not share her customer list due to privacy concerns". So maybe JPM could have pushed back against that more?
"""Javice also cited privacy concerns in sharing Frank’s customer data directly with JPMC. After numerous internal conversations, and in order to allay Javice’s concerns, JPMC agreed to use a third-party data management vendor, Acxiom, to validate Frank’s customer information rather than providing the personal identifying information directly to JPMC."""
