U.S. Supreme Court rebuffs Facebook appeal in user tracking lawsuit
<i>“Facebook was not an uninvited interloper to a communication between two separate parties; it was a direct participant,” the company said in a legal filing.</i><p>There's gotta be some existing legal doctrine on what constitutes a "direct participant", right?<p>Suppose I visit the website of Company A intending to do business with them (perhaps this is the only way to contact them). Their website contains the Facebook "like" button somewhere on the page. Is Facebook really a "direct participant" if I have no way to know that their widget is even on the site until I visit it, at which point they have already participated and I have no way to avoid it?<p>Likewise, does the law/precedent on "expectation of privacy" have anything to say about who specifically I should/shouldn't expect privacy from?
