I'm not a politics expert, but I'm pretty sure that what you're describing is not socialism: the Amazon customer community owns nothing of Amazon, regulates nothing for Amazon. Amazon is just bundling services in such a way that they can get people who are keen on one of those to pay for the others that they're not keen on. So someone who really wants the TV option will take Prime, and someone who really wants the delivery option will take Prime, both at a higher price than they would for those services alone, and so Amazon gets more money out of them than they could if they offered the TV and the delivery separately. That's describable by many terms, but it's not socialism.
