For money, my dear, for money. Is there any other reason for a company to exist? The stuff like "do no evil" or "we are green" is just a smoke screen. At the end they will do everything for money.
I was under the impression that pre 20th century companies just existed as a legal and organizational convenience in order to help collect a number of people with similar goals rather than to solely make a profit.
If anything, the drive for profit is a little less now.
