You cannot divorce a product from the people who built it. The product reflects their priorities and internal group well-being. A different group of people would have built a different product.
With that said, it's also not correct to claim that line folk have no influence at all. I don't believe that you can blame any individual since they may have stood up against something bad being put in the product, but they're still part of a collective group of people that built a bad product.
