They're made out of people subservient to the owners, whether that's a rich dude or a bunch of shareholders largely shielded from the day to day operations and who just want their stocks to go up a little more. Google is THE poster child of a company whose employees rebelled, even unionized, but who still don't really have much power.

It's a huge advertising company trying to make more money, not a scrappy search tech startup in a garage...

It doesn't matter what corporations are made of, they are their own different thing operating in a different context and according to other rules.

It doesn't matter if it's made of people or ants.

Yeah good luck with that. The founding principal and mission of a corporation is to make money at all costs. Being "Good" will always come second to making money, the individuals who make it up are powerless to stop it.
