There are _some_ limits to that. If a company is deemed to be considered the equivalent of a town square, it can be given the same restrictions as the 1st amendment. For example Malls cannot ban protected speech in their premises. If a company is not deemed this by courts, they have the full right to ban you for non-protected reasons (excluding racism/sexism and so on)
