Why is Discord recording our open programs and uploading them?

If you monitor Discord using an application like Process Monitor you can see it run "QueryNameInformationFile" on every program you have open, and then it proceeds to take the names of everything you have open (this includes the titles of all your browsing windows) to the following address 108.61.16.132.choopa.com over tcp.

Blocking 108.61.16.132 results in the program disconnecting.

Is it necessary to record everything we have open and send it your servers? This seems like a pretty big breach of privacy.

Is there a way to disable it from spying on us?

Edit: Please see the response below from discord's CTO and other employee Jake, plus my response regarding what is being sent (that we can determine). TL:DR It's not a list of your programs, more of a ping for socket connections, but the software still does scan your applications locally.
