Botnet
If you are on the Internet, there are chances that your computer might be part of a botnet. Also, /g/entoomen often refer to Google, Ubuntu and other companies/products which track user behavior as botnets.
Most of the time, however, the software in question isn't anything even remotely similiar to an actual botnet, and just offers less privacy therby greatly reducing your freedom.
