That looks like a link where facebook has replaced the link to the website with their own URL for tracking purposes. As a consequence they have to prevent open redirect attacks - https://www.owasp.org/index.php/Open_redirect https://www.owasp.org/index.php/Open_redirect . Yes the same system can be used for censorship - but facebook can do that anyway because you're sharing links through a platform they have total control over. The irony (of using a facebook tracking url to promote an anti-facebook site) is beautiful.
