IT guys will stop using it...

No, they will not, if they didn't already. Because convenience it key.

The browser war is over, and humans lost, corporations won. Google and other huge corporations control the biggest websites and most of the access to content on the internet.

They just need to make it inconvenient to use ad-blocking browsers.

They built their business on advertiser gambling, which seem to be flawed concept, because they keep on squeezing that tube for every penny more and more, in a race to the bottom.

But they are still in control of both browers and content so they have options to keep squeezing more.

So you want to use a ad blocker? Well, the browser that supports them might not be white listed (anymore) by the bot detector, and you have to solve captchas on every site you visit, until you come to your senses and use a browser, where ad blocking is no longer possible.

Oh, and all that is ok, because of "security". Because letting the users be in control of their devices and applications is "in-secure". They are just doing that to protect you from spam and scams, just trust them! Trust them, because they don't trust you!
