People do it for pirated copies of Adobe software because of how much it phones home. Do a quick google search and you'll find many sn/crack/warez (do people still use that word?) instructions talk about editing hosts files or installing Little Snitch.

How did you get around not having live.com for MS Office? I've got the retail box of 2016 for Mac (not the 365 one) and it still required me to make one :(

At every launch, it connects to login.live.com and live.com.akadns.net.
