Unfortunately you ARE saying that. Think about it for a moment. By only containing "convert to Pathfinder" you are in essence placing Pathfinder before all d20 OGL products. You are saying Pathfinder should become the lingua-franca of the d20 OGL fantasy rule set and should be revered above the d20 OGL SRD itself.
It renders that product biased (beyond the assumption that the editor thing X product is the best of the 2000s). Now if it was Piazo publishing it, I wouldn't question the motives behind doing such a product, but if they weren't responsible then I start wondering why the product is only containing rules to convert to Pathfinder instead of Trial Blazer, d20 SRD, Black Company, Book of Experimental Might, etc.
