I felt like Google played dumb with the drug ads thing and didn't really hold people accountable (Page was hardly rebuked) -- here they need to come down hard to show that they're serious about "Don't be evil" -- or is that just a useful motto when you're the young underdog.
You're a business and a public one at that... that means you'll do anything for profit, just like every other company.
As a company director I repudiate this so hard.
Most companies? Most-probably. Every company? Not at all.
Google's two-tier share structure specifically means they do not need to act in anyway that Page and Brin don't want to.
Even if every other shareholder hated everything they did, Page & Brin's shares will always out-vote them because each share they own is worth 10 votes of anyone else.[1]
