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]
[1] "The actual voting power of the insiders is much higher, however, as Google has a dual class stock structure in which each Class B share gets ten votes compared to each Class A share getting one." http://en.wikipedia.org/wiki/History_of_Google
