If you've worked in a large company, you know that the product reflects the priorities of the company so much more than the people who work there. Leadership states the priority and the employees do what they're told.
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.
