I tend to personally view things from the owner's point of view. I also know that once the popular narrative has bitten down on the story of a successful company running slave factories, they won't let go. Whether these are exaggerated or isolated cases doesn't matter, there will be story after story until Amazon makes some show of changing practices.
However, I know there's another side. At some point, a company the size of Amazon begins consuming all available oxygen. I don't know what the tipping point is, but I know workers in some areas have about as much choice in where to work as I do in cable providers. That's obviously undesirable, because without a competitive labor market, Amazon is in practice able to treat employees however they choose, because the one emergency brake built into the loop is gone.
I wish there were some simple way to codify regulations about employee treatment once you become as powerful as a small nation that don't also encumber 150-employee plastic tubing manufacturers. At that level, pure laissez faire is desirable to me, because you do have options as an employee, and no reasonable case can be made that you've got to bog down your employer in a regulatory mess. Then, once you've got some single digit of the GDP in resources, you can be expected to operate with increased oversight and expectations, as a tax for the opportunity cost your mere presence visits upon other firms.
If that inhibits growth of megacorps... well, that's OK.
