>The government can’t just stop letting businesses incorporate because it doesn’t like how a county voted.

The government can revoke a corporation's charter at any time it desires to.

No it can't. It must comply with other constitutional obligations like the equal protection clause and 1A. Basically any action to revoke the charter of a single corporation (or group of corporations) for any reason other than violating pre-existing law is going to be very hard to justify in court. And threatening to leave the state is clearly not against the law (nor could it ever be because that law would violate 1A). Furthermore, even if a state is able to revoke a corporate charter, it can't stop it from re-incorporating in another state and continuing to do business in the original state under its new charter (commerce clause).
