This sort of freedom only benefits capitalists, at the expense of everyday people, and threatens democracy itself. The employer-employee relationship is not a partnership of equals, especially in places like the US where lack of employment is pretty much a slow death sentence.

A company isn't just a bunch of people who want to work with each other, unless it's structured as a worker owned coop, partnership, or similar. More often than not it's a legal institution created for the express purpose of extracting profit by extracting value out of poorer people's labor. There's no inherent "freedom" for any such entity, only what society chooses to give it.
