"It would cause major harm to the companies like online advertising networks, small and midsize publishers and technology companies like Yahoo that earn a large percentage of their revenue from advertising that is tailored to users based on the sites they have visited.
"Under a situation where many users opt out of being tracked, other companies, like Google, may take a much smaller hit because the vast majority of its revenue comes through search ads that would not be affected by a do-not-track mechanism."
Can anyone explain how Yahoo! is different than Google, insofar as they could be affected more severely?
