There is something called the duty to protect. Copyright holders have the duty to protect their work, or they may find themselves unable to win any court case for a copyright violation.

If TB’s wife doesn’t have the financial resources to engage in a legal offensive, then this may be her only option. Though deleting all content would be a mistake. If the content no longer exists, and she’s the one who deleted it, then there’s nothing to go to court over.
