You have an issue with customer behavior so you set up tracking to understand it. Keep it running for a few days, then check on but the tracking doesn't output meaningful data that you can exploit to solve your issue. At this point, you search for alternative tracking but do you disable the old one ? What's the benefit ? Either it's free or cost very little, none of your customer know they are being tracked and in the eventuality it may become useful later on you keep it. Repeat a few times and you end up with bloated website that tracks where you were, are and will be. What you're watching, cursor position, scrolling, how long you spent watching that image or these one, have access to every technical details about your device because it's required for fingerprinting, all while no one actually is exploiting the data. It's junk yet you collect it because it's free. If there was a meaningful reason to limit the number of tracking, like the law and fear of getting sued, then it would be a different story.
