Good products are usually driven by commercial entities. I would love to use something else besides Android or iOS that is not backed by a commercial giant, which WORKS, is not full of spyware and has a healthy ecosystem but nobody is making one, nobody is able to put 2 and 2 together there.
Are the products you buy online going to physically move differently when you use the "decentralised" internet? Are the small businesses going to revive because of that? AMZN did not kill them, the consumer did. It's the consumer that spends the dollar and dictates such outcomes - none of which are going to be fixed by Web 3. For me, the centralisation that amazon provides is a feature, not a bug. You will not kill AMZN until you understand why it works the way it does and start competing with them. Don't tell me it can't be done because AliExpress is giggling in the background.
I have a few friends doing a fortune on AMZN without even seeing the products they sell (FBA). Adapt or die, it's just nature.
