Well, for one Google blocks popup banners with their toolbar and then turns around and sells paid ads.
Google's business model seems parasitic as its entire business is based on using other companies' and individuals' content without their consent and without compensating them. That was 'ok' since the Internet community in an informal way agreed that the concept of Web search, spiders, and crawling is in general very useful. But Google is no longer simply publishing headlines and links; with its cached pages, it is taking the entire content of other sites and displaying them on Google, without permission and worse they filter it to their need and liking.
Does someone know of a good tool to undo their system and block their ads?
Is InternMute any good?
