"But why?"
Why not? MSN Messenger was onve the ultimate king of instant messaging and social networking programs, in a time before Facebook, Skype, Discord, or Twitter. But then Microsoft bought Skype in 2012 and thought that owning two seperate chat services was redundant, so MSN was shut down. Which is a shame, 'cause even though it might not have the latest features, it still is a good IM platform. Now several people are working on reverse engineering a server for every major MSN version, and you can chat with people all over the world right now!
