Until Facebook drops the pretense and begins spreading as a viral botnet. What can your precious hosts file do, when everywhere you point your browser, all you see is the Face of SkyNetBook?
And there's no login required; it already knows who you are. It has already read, analyzed, and posted on your timeline all your formerly private files. Full details of everything you do will be instantly available for the world to read with no interaction needed from you, since SkyNetBook is everywhere, on every computer, every CCTV, every smartphone. And naturally SkyNetBook has your billing information, so anything that could be considered an affirmative for any of the... commercial suggestions SkyNetBook presents you results in automatic order. Just think of the benefits for economy! And since everything you do is documented, you don't need to fear death, for your profile will be kept active and run by the same commercial AI that makes the suggestions, so you - or your profile - can keep sending invites to your friends.
It's just you and other dead people, on Facebook, haunting the living with FarmVille invites, forever.
Also, from my POV, the only "independent sites" out there don't depend on external ads. The others are, by definition, dependent. Like this one.
Every site depends on some kind of income stream to cover its expenses, be it ads, subscriptions or the publisher's pockets. So either conclude that "independent site" is an oxymoron, or lower or refine your standards a bit.
