Long before Snapchat was a huge deal, it was the subject of a buyout deal from Facebook chief Mark Zuckerberg. Snapchat rebuffed the offer, and Facebook's response has been to work relentlessly to undermine the object of its jilted affections. Instagram has been slowly drawing inspiration from its main rival, adding Instagram Stories to its core platform. In addition, Facebook tried to buy the "Asian Snapchat" this summer in the hope of curtailing its rival's international growth. It's a lesson to us all that if Mark Zuckerberg offers you $3 billion for something, maybe factor how much revenge he'll exact if you say no.
