When you're logged into Jonny Wonny and you're scrolling down your News Feed, how come a post from VICE is there (3:19 & 3:16)? You had to like VICE in order for it to appear in News Feed. So your whole argument is false.
A friend could have liked a brand years ago and it could just be showing in your News Feed now, it doesn't have to show based on when they liked it.
