Bezos made a better web interface for a Walmart level selection of goods and now Walmart is caught up and it's all the same. Shopping at Amazon is ethically the same as shopping at Walmart (not good IMO).
how is Walmart "caught up"? this is what their homepage looks like today on my pixel 4a: https://ibb.co/Y3Zh7k2
if I flip it to landscape, the layout looks right, but the button to reveal the search bar (the most important element on a retail homepage) doesn't work. I would be shocked to have that experience with Amazon in the middle of the holidays. it's just throwing away money.

They're caught up exactly because your biggest problem is that the site layout shit the bed. Your complaint wasn't that their business model and logistical infrastructure doesn't let you order stuff to your home on par with amazon.
it might seem like a minor issue. if I really wanted to shop with Walmart I could try a different browser, try their app, or switch to my PC. but people don't do that when they just want to buy something. approximately no one cares about giving second chances to a megacorp.
when you have strong competition, it's not enough to mostly get things right at a high level. the little things matter just as much for earning trust. Amazon gets this. Walmart, apparently, does not. they're a solid second choice if something is sold out elsewhere, I'll give them that.
