Ads are what make the internet a bloated mess. Ads are why there are a thousand different results for “roasted broccoli recipe”, because they are all trying to get me to pick them so I can see ads. Its why each one is 5 pages of crap before you get to the actual recipe, so they can shove in more ads. Everything is stretched, duplicative, and needless complex, so you will move through as many ads as humanly possible.
Sure, I don't mind the ads. The pervasive tracking and data collection and profile building is where I draw the line. Tons and tons of JS churning my browser to sell me stuff. If my adblock eventually causes some sort of economic disaster, so be it.
