You're talking about one aspect of businesses -- their relationship with their consumers, which generally is not exploitative (although there are obvious exceptions).

However, Jeff Bezos's relationship with his employees is exploitative (especially warehouse employees). Consider also his relationship with publicly-funded research. We as taxpayers pay for public research, we helped pay to build the internet, and yet we don't see any dividends for that money.

Also, the mere fact that one person controls that much wealth is problematic politically. Jeff Bezos owns one of the largest newspapers in the world, which concerns me greatly. He has tremendous political influence in Seattle, and has been able to bully other cities into giving into his demands for HQ2. Massive amounts of wealth comes with it massive amounts of power, and power is a zero sum game.
