Fingerprinting can be very useful to you as a user, as well. Imagine that you switch between devices and work locations all the time and you use a core suite of web applications. Fingerprinting could be used, with your permission, to uniquely identify you across all your devices, locations, and browsers for the suite of services that you depend upon. Not having to ever enter a password again while remaining secure sounds pretty nice to me.
It is not the technology, but the evil application of said technology that is evil.
