The original article link to http://www.SaveTheInternet.in is actually to http://l.facebook.com/l.php?u=http%3A%2F%2Fwww.SaveTheIntern...

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 .

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.
