When the US government finds its responsibility to limit the power of its companies (unless you are of the belief that their power should be unlimited), come back to me on that.
Companies are a tool that should serve the public, if they cease to serve the public, they should be bought in line, destroyed, or (as is threatened in this case) exiled. A democracy is meant to be for the people, not for profit. Profit is just a motive to try and incentivise things that are valuable for society, when that isn't achieved, regulators should step in to fix it.
Companies that are too large have too much money, and too much power. They are inherently anti-consumer and cause harm to the very fabric of democracy. In any sane world, we would be breaking up a huge number of these large corporations into much smaller pieces.
The electorate has a responsibility to protect democracy and not let companies break the law of the land, they have no responsibility at all to companies.
