I forget where, but somewhere I read that at large companies relatively small optimizations can be worth millions of dollars. Because of that, it's worth it for these companies to apply a lot of engineering resources to optimization problems (including developer experience). I know you're not saying this, but I'd caution anyone against saying things like "<company>'s product is just a glorified <something simple>". It's very hard for people not working directly on a product to truly understand its complexity and everything that goes into it.
