Re: No f in button?
The button is a "share on Facebook" button, which is why it requests you log in in order to complete the operation. Same goes for all other login protected sites you'd want to share an article with via the widget: if you aren't logged in, and the site doesn't allow sharing links anonymously, you'll have to log in to use it, and "be tracked". Somehow it doesn't scream as much "dark pattern" as what the article talks about w/regards to the "like" button which instead allegedly tracks by default?
