It's actually funny because the introduction of this article makes it sound like Tom's are the Mafia and are slyly trying to tell ASUS they would get better reviews if they gave them the motherboards free haha.
If that's your takeaway, you're reading WAY too much into it.
Products are submitted for review in many ways. Most often the manufacturer simply sends in a sample. Sometimes they ask for the samples back, sometimes not. But no one requires the reviewer to buy the product first ( "Hey, Car & Driver, we'd love for you to test drive and review the new Porsche / Ferrari / Lambo, but you're gonna need to buy it first." ).
When Tom's wants to do a product review on a certain range of products, they send out an open invitations to every manufacturer. No one is excluded. If a mfr responds saying they want to participate, they can make any special request at that time and each are handled individually. However, some mfrs don't respond at all.
More common is for mfrs to initiate contact, saying they have a new product launching and offer to send us a sample. However, sometimes we see a product requested on the forums or other places that was not submitted to us. In such a case we may purchase it directly for review ( or possibly the reviewer pays for it out of their own pocket because they want to review it that badly ).
If you want to criticize a review for its methodology, missing factual points, or on empirical data, go ahead. Saying a writer or Tom's as a whole is on the take or shilling products for company A or mfr B without proof is a big no-no.
