Bump. I wanted to say that ads are not that bad, ofcourse not all, but some are legit and it helps to maintain a website/have some revenue, on mobiles it helps developers have some income to support their work, they don't invade anything and just display ads... admob is probably the biggest network which I use as well in some of my apps and I tell ya that extra 40euro/month doesn't go to waste.
Same goes for websites - ofc no one likes the penis enlargement bullshit lol, those should be blocked, but legit advertisements shouldn't be completely blocked. And someone said that if the website needs ads to stay up, they are doing it wrong? well not completely, as I said, the project could be awesome, but offering it for free ain't going to pay back the hosting and other expenses. People aren't willing to give a lot of money in donations unless the service saves their lives, ads help developers gather income to pay back some of the work and that's it.
