Yeah I don't think this is the best analogy, but the point being is brand loyalty can only go so far. Like if you're going to run out of gas in the next 20 miles and there isn't an Exxon station within 100 miles, do you just pass all other gas stations and have your employees break down on the side of the road?

I just can't imagine any actual competitors to AWS would impose such restrictions on their employees that put them in a worse position to do their jobs, so it's a bit silly that it's coming from Walmart, when they don't compete in that space.
