Yes, there are ways to get around fingerprinting defenses. But that is not
a reason to not implement defenses in the first place. You close hole by
hole raising the bar for the attacker. Remeber: you don't win the
fingerprinting game by closing _all_ the holes but by making it hard
enough that trackers lose interest in this technique and/or don't get
usable results out of it anymore.
