The problem may be murky, but the solution is a bit more clear, if not exactly novel: build a better product. Not a fancier iPad app, a better ad product. For all the haranguing about native ads, they have the advantage of being immune to filters and, when done right, a genuinely better experience, certainly better than green double-underlines or the “content marketing platform” ads at the bottom of far too many web pages.
Just give me a well designed, compelling advertisement. Hell, I’ll share my browsing history if that is what it takes to serve me something I’m genuinely interested in.
