You can view it as an Apple vs Google move if you wish, but the plain fact is that the user experience on most major (and minor) web sites is atrocious.
What should be 50–60k of content is surrounded by megabytes upon megabytes of banner ads, pop-overs, pop-unders, interstitials, embedded auto-playing video, tracking scripts, and other forms of “rich” media content designed to grab and track attention in any way it can.
Keep in mind that Apple only enabled the capability for ad blocking in Safari.
And Apple isn’t forcing its users to download those apps. So the fact that ad blockers are currently first, second, and third in the paid app category should tell you all you need to know about just how many users happen to agree with them.
And death of the web? Mmmm… perhaps the web as we know it today.
But given the current state of affairs, I’m not really sure that’s a bad thing, after all.
