Ask HN: Structure a company so that it legally cannot be acquired by Facebook?

Is there any way to structure a company, or something we can do, so that it legally cannot be acquired by Facebook? Something beyond just making a pledge. Also, is there any precedent for this or companies you know of doing similar?
