They can enter new industries well below market cost and destroy all of the existing businesses. They then soak up everything. In the end, everything becomes Amazon.

They did it to open source, bookstores, retail.

Maybe you don't see the end goal, where every restaurant is Amazon and you rent your home from Jeff Bezos?

Maybe you're not worried and you trust these people?

Maybe you don't want to compete and you just want to be an employee?

I don't know. But this is wrong. You can't compete with this, you're forced to work with it. It decreases degrees of freedom and angle of attack for everyone else.

From Amazon's perspective, their moat becomes an ocean. That's hard to swim in.
