Is money earned from commissions in the modified network marketing system, which sells products at market prices without subscriptions or membership renewals, forbidden or permissible?

We have previously clarified in numerous fatwas the impermissibility of multi-level marketing due to its inclusion of usury and gharar (definition) (excessive uncertainty). However, if the situation inquired about involves a company selling a permissible product, and marketing does not require a financial subscription or the purchase of a product, and the commission is known, then this is permissible; otherwise, it is not.
