How can financing from an interest-based bank be considered "blessed" and permissible, and does using this financing in permissible (halal) companies make it permissible?

It is mentioned that borrowing from a usurious bank is permissible if it is without a stipulated interest, and there is no impediment to a usurious bank providing a permissible service. However, if the loan is usurious, the borrower is sinful, but if it is invested in a permissible trade, the generated profit is permissible.
