The whole philosophical backing of both "freedom of speech" and "innocent until proven guilty" is that the government doesn't itself have civil rights, only the rights explicitly outlined to it in the founding documents of that government (e.g. US Constitution).
Once you venture into private parties evaluating other private parties, you encounter a collision of rights. It's still freedom of speech and association to not want to do business with certain people, and as long as those certain people aren't of a protected class, this falls well within the moral concepts of both free speech and presumption of innocence.
