I dont like this kind of stuff, but here are some devils advocate ideas why it is not illegal.
I can take a copy of time magazine that I find laying on the street and If I dont like the front cover i can get some glue and paste a picture of my face on the front cover. I have therefore edited time magazine to see it the way I want to see it. I can also alter the fonts on all pages on the interent to view it the way I want to view it. I can choose to turn images off or on on all websites. Does this mean microsoft browser is infringng on the way you display your page ? I dont think so ! So if you follow that thinking If I buy a peice of software and I agree to have that software change the way I veiw the web, then that is the same as having microsoft hardcode fonts into the browser default fonts. or me pasting a picture of my face onto my screen or inserting my picture digitally onto every page I view with a layer....
The point is on an individual basis I have the right to choose how I view your site. Now if I was able to edit your contnet so everyone who lokked at it had no choice but to see my ads then you could sue the fuck out off me.
Anyway this is all a gray area of the law and has not yet been proven right or worng. only a fat lawsuit will fix this.
But Google won a case where they can take all the images on your site thumbnail them all and put all thsoe pics on their site.
linking direct to the main pic. bypassing all of your ads.
Just stuff to think about in the digital age things are still new even if its been 10 years comin
