If you are young and blessed with no dependencies, you should attempt exploiting higher risk domains. As you get older with more dependencies, you need to lower your risk tolerance. The technical term for this is exploration vs exploitation. The maximum payouts in many complex system requires some balance between two and sticking with just exploitation is often not the optimal policy when you look at life span as a whole.
My weak sauce rationalization re Amazon is that I wouldn't work there (I love hearing the big sigh from recruiters when I ask if the client they are hiring for is Amazon.)
Others who choose to work there do so voluntarily. They haven choosen their own pain.
In my mind this is different than using your PhDs to build dark patterns to trick consumers, survelience tech to monetize people, using that surveillance information and neuroscience to manipulate people, and so on.
edit: to add -- I forgot about Apple, since I stopped buying their stuff a few years ago. At least they see that privacy protection may have some value in the marketplace.
