That's a really interesting proposition and one that I think bears looking at.
Facebook and Google are effectively trying to become privately owned utilities, aka natural monopolies, for access to the internet. Facebook with their internet.org and google with googlefiber. So there is a case to make there for those companies being looked at like utilities.
However I'm not sure how Amazon fits that narrative. Amazon Marketplace is a tiny chunk of their sales revenue, despite it becoming the largest part of their fulfillment. AWS isn't infrastructure in the same way as facebook and google are trying to do.
I think it's too far a reach politically - they can't even get ISP's classified as utilities.
I think the major problem here is that because these companies don't need to operate from a fixed location in the same way a steel mill, power plant etc... would that there isn't really that many ways that the government can muscle them. They feel the pressure and they just pick up and move (legally first) or shift workers around. So regulators don't have a framework for how to muscle these companies in the same way as old industry.
