Only one of the sites to which you link above actually claims to offer “free” textbooks. However, in reality, about all that is free is that one can read most (but not all!) of their content online. They are licensed under a restrictive license (one which, ironically, would require a university to pay to use them for a course), and important features and course materials are left out unless you pay (a “freemium” model).
