Hey websites, I notice you're making it harder recently to view your page with adblock or noscript running.
You have to remember, people are on your sites because they happen to be bored at the moment. They are not interested in playing whack-a-mole to figure out what silly bit of Java will let your site load.
They'll just click the back button.
Careful, they might actually find out the real world is more interesting. :P
