I agree with the other commenters that "common sense is remarkably uncommon." Yes, once you've grasped how web cookies and iframes and other mechanisms can be combined to track you across web sites, it is obvious that Facebook can track you even if you don't click the "like" button.

But most people don't have this level of understanding, and I'd say that Facebook goes out of their way to make this non-obvious. So yes, you're right, but also yes, this type of article is relevant. You probably read something like this once, and it was a revelation for you. Now others are getting their tall, cool, glass of reality.

No idea why you're getting downvotes, unless people equate your comments slightly dismissive tone with being non-contributory. Personally, I've seen far worse, and you have some useful tips embedded in the comments, so as far as I'm concerned your comment is a win. Thanks.
