Delete user post (products)

Got so far that I need to change “delete_with_user” post attribute, the question is how?

WooCommerce creates its own database tables
https://github.com/woocommerce/woocommerce/wiki/Database-Description

I have no plans to begin deleting from custom database table data created by WooCommerce.

I would suggest you ask WooCommerce for the option to delete the WooCommerce data when a WordPress delete_user action is done.
