If companies don't send him review units then he just buys them retail. He has already done this for many products.

Yes, I'm aware. That's less money in his pocket, and less ability to have the review be available on or before the product launch. There's still some conflict of interest, even if it's lessened.

Only purchasing review units at retail would remove this conflict.

Incorrect. He can then return them.
