Yeah, it must be fun being sarcastically dismissive of criticism when you aren't the one getting the short end of the stick (or maybe you are and don't even realise it).
Trampling workers rights, unloading externalities onto taxpayers, establishing dangerous dominance in many sectors, wiping your ass with user privacy, hugely increasing pollution to deliver packages a day earlier, just a few examples of what it costs to ship you packets of cheap crap within 2 days. Dismissing all that because you appreciate the convenience of free 2-day delivery is the purest expression of first-world privilege.
