It’s because it isn’t spyware. There is no kernel level anticheat or admin requirements as people keep suggesting . And the only things it sends back to gearbox is related to game functions:

• your steam friends list so it can check if they have a gearbox account
• in game chat
• which level in the game you’re currently on

I literally went to the point of packet inspection and found nothing to be concerned about.

EDIT: clarified reply was about it being called spyware.
