>Amazon always claims to focus on its customers, and ignore its competitors

That's not what Amazon claims. The actual Amazon leadership principal is: "Leaders start with the customer and work backwards. They work vigorously to earn and keep customer trust. Although leaders pay attention to competitors, they obsess over customers."

I also don't see how this is "focusing more on its competitors". Amazon had previously identified a plan for Kuiper to serve its customers, and SpaceX interfered with that. The tactics to do so are debatable, but I think it's easily arguable that this protest is in the interest of serving its customers.
