What's unbelievable is the audacity of these companies. Programmers want to improve performance for everyone so they come up with caching mechanisms. So what do the companies do? They abuse the feature in order to track users.

The ability to clear browser data is not quite enough. Caching should be disabled by default in all browsers due to the potential for abuse. Oh no, now companies are getting less conversions and sales due to the loss in performance... Sucks to be them. Actually the more their abuse costs them the better.
