We can extend your point. A website used by kids may not want swear words, a website may not want sexists, racists, and another hate speech. In certain situations, disallowing content is the site owner's way of expressing their point of the view. This law bans this site owner from doing so. It limits site owner's ability to express their views on what their own property should be. By the way, we should also keep in mind that a site is the private property of an entity, just like an object or a piece of land. If this law is enacted, when a site owner sees speech on their own site that goes against their values, they can only condemn them with words, but the actual act will still happen on their property.
