Re: View from inside
There are billions of ads served every day globally. Given the widespread belief expressed here of the quantity of malicious ads running scripts and taking over your life then there would surely be countless stories of thousands if not millions of people being hit by 'malvertising' and 'losing all of their data'. I must have missed them.
Of course, if you are a complete tin-hat wearing lunatic you would probably believe that there was a global conspiracy to keep it out of the media.
Or, on the other hand, maybe this non-existent/infinitely low risk possibility is used as an excuse by people who just can't express the prosaic truth that 'ads are annoying, blocking them is easy, so I do it'.
