Heh... I use ABP.... heck, I use it here. I hate the ads on websites. Very intrusive. But I contribute to 90% of the sites that ads are on. So if they want to block a massive contributer, then they can do so, but it's on them 😉
It's not breaking the law, not matter how you look at it. Take the news paper. Notice how many ads are in there? And how many people pay attention to them? Like 10%? Or how about TV? Are they going to block DVR or fast forwarding through commercials because then they're getting "free" cable? I remember when cable meant "no ads", and that's what you paid for.
Stupid stupid people are trying to fight this, and even stupider people are following along. Next thing you know, as you're playing a video-game or watching an HBO movie, an ad will pop up for 2 to 3 minutes saying "Hey, buy my product"!!
What really brought all this on were those javascript and CSS hack ads that floated over everything so that you couldn't read the page until you acknowledged the Ad. Inline ads (like here) are not so bad; except that typically they slow down my load times. But I mean come on, the ad makers brought this on themselves...
