That's an anecdotal example. Amazon is different in that Bezos has enough room to dial back reinvestment and generate more cash or turn up reinvestment to reduce apparent profit.
Profit doesn't just magically appear, costs and pricing have to eventually face reality. Sooner, the better.
Spending more money does not necessarily make a business any better. That's like these noob business people that buy stock before they sell any of it... An example of a horrible waste of cash.
Without profit, it's not a business, it's an idea-guy dream.
