That's what businesses do. They are created to make money. They only way to keep them in check is with regulations. The unfortunate thing is so many people hold libertarian views while others are anti-big government.
The difficulty is knowing which checks are necessary and which are "big government". Which is why we vote.
Being anti big government is not the same thing as being anti all government. Characterising it that way is either lazy or ignorant, take your pick.
But just as the winners write the history books, the richest libertarians like Thiel and Koch seem able to define what the ideology looks like in the popular imagination, because they can afford to shape the debate via think tanks, media ownership, campus outreach, lobbying, etc.
