Empathy not included, but Docs says so.

[computer_freak_8]

The official documentation lists Empathy as the default IM client, but in fact, it's only available in the universe repository, and certainly not installed by default.

https://help.ubuntu.com/16.04/ubuntu-help/net-chat-empathy.html

ubuntu@ubuntu:~$ empathy
The program 'empathy' is currently not installed. You can install it by typing:
sudo apt install empathy
You will have to enable the component called 'universe'
ubuntu@ubuntu:~$

In the lower-right corner of that page, it says "To report errors in this documentation, file a bug.". I clicked the link for "file a bug" and it led me here. According to the included search features while filing the bug, I'm the first person to report this.
