HI, John. Your argument would be valid if Facebbok was a public company, but it is not. It is a private corporation that is funded by those who invested in its potential. What they do to make garner profits is their business. Since the platform is free for general public use, the way they use information is users give to use the platform is allowable. After all, we have a choice of not using the platform if we do not agree with the use the information. As long as Facebook does not promote racism, religious superiority, bigotry, or violence, it is all fair game. There is not psychological manipulation outside of their promoting their platforms to gain more users.
