I recall reading somewhere that Google's own research revealed that less than 2 % of Chrome users worldwide installed adblockers, so they were content to leave the issue and let people continue using adblockers. For now.
I mean, one has to wonder how a company whose main form of revenue is from advertising allows add-ons that threaten that very revenue stream, and on their very own flagship browser. I guess they know it's just the geeks who do it. And a few of their friends.
As a pc tech I see lots of pc's, probably thousands over the last 10 years, and I can't recall a single one of them having an adblocker installed. That is of course those who are using chrome or firefox as the default browser.
