So, using a free web app with ads and a paid option (think flickr) is ok, using a free mobile app with ads is ok, but when it's a desktop app it's no longer ok?
This is not about doing shaddy techniques / crapware / spyware. This is not about changing user settings, installing toolbar, sniffing on user's activity, etc... It is just about displaying relevant text link ads inside a program you enjoy using.
I know many will disagree with me, but I've always had the feeling that advertising on mobile apps is there to exploit user distraction. I haven't got any source to back my theory, nor any conversion rate stats, but I would say that a big chunk of clicks come from user mistakes, rather than genuine interest in the ads, and the same would apply to desktop applications imo.
This might happen on the web too, but with a lower order of magnitude, since the average internet surfer is more likely ready to evaluate an offer/purchase.
I adblock wherever I can as I value my privacy. Ads also are an distraction. My desktop browser is blocking ads. I rooted my phone to be able to block ads. I switch channels or take a break when ads come up on TV.
