Or a marketing department worked with an agency. Not representing my company, etcetera, but some agency ours used turned on all the default settings, and rarely goes back to turn off trackers for campaigns they're no longer running. When someone in house was managing he had only turned on what was required, and cleaned up old campaigns. I also worked with a user Friday who had noticed links via emails were no longer working. Turned out ublock/Firefox was stopping at the iContact tracking URL. She wasn't sure who to report it to, and wasn't using iContact for her emails, so sat on it until she ran into it when we were meeting. Based on personal experience, marketing groups usually use whatever their IT department approves, and if they're managed, certain browser settings are being pushed to whitelist these based upon users saying things aren't working. Easier to just push a setting than explain best practices.
