As an investor I'm not looking for Thiels "sustainable business strategy", I want growth. New products, new markets, pushing the envelope.
And that comes from taking risks,, shipping, and dealing with failures. Google and Apple are simply not doing that in a meaningful way, and their share price reflects that.
I'm not sure I agree with this about Amazon, but some of it may just be strategy opinion differences. Apple and Google both have higher capitalizations, but more importantly they operate at growing profits as opposed to a loss. Google's share price is also substantially higher than Amazon's.
Bezos has definitely made some good decisions, but I think attributing too much to one person (correct or incorrect) is a bit of a problem. Either the company fails without that person, or the perception is that the company can't succeed without that person.
Regardless, my personal opinion on Amazon's overall retail strategy and execution is honestly pretty bad.
