There were no adblocking extensions for early internet explorer so consider its share 0.
What you consider it to be is irrelevant. An extension wasn’t any more the only way to block ads then than it is now. Ad blocking has absolutely been happening longer than there have been extensions to do it.
Adblocking increased at twice the rate of new internet users
Which means it’s going to reach a critical mass at some point, no? What would you expect to happen then?
very obviously trolling or roleplaying
Damn am I sick of people falling on this regardless of what the disagreement is over or who it is with. Even if it were true, which it’s not, you have a better picture of the situation, at least if you’re willing to accept that someone legitimately disagrees with you.
