I've liked, and still like Google, because they have a high sense of business ethic.
Did Microsoft or yahoo pull out of china when it was getting hacked?
Did Microsoft or yahoo contest china's censorship programs?
Does Microsoft, Yahoo, or Apple make exporting data/contacts you create on their platforms exportable should you wish to migrate away?
Does Microsoft, Yahoo, or Apple offer free api's, allowing 3rd parties to access and interface with their services and user's data?
Does Apple operate a store which is free to publish on?
Does Apple have a phone that is unlocked, easy to perform maintenance and connect to, and doesn't attempt to brick jailbroken phones each time a firmware update arrives?
How about how Google tries to protect the freedom of the internet, adding its weight to net neutrality, patent reform, and other legal issues that plague the future of IT.
"What happened to the Google that just had a cool search engine? Why is it taking advantage of search monopoly profits to either buy out or crush every competitor in every non-core market? Why do they talk about openness when their core business is based on a search and advertising engine that is not open source?"
Google grew, advertising is its key business and like all businesses it does what it can to protect its review stream. But its doing it in the most honest way a business can, buying out or just beating via prices.
Its not sending lawsuits with patent infringement shakedowns like every other big company out there.
As for openness, there is no reason, legal, ethical, or moral, that google should reveal their search engine source code. In fact the only thing that would do is improve search functionality of their competitors, and help link farms be more effective.
Google is a saint compared to every other mainstream IT company out there.
It’s not perfect, but they actively try to be good AND profitable. It’s not an easy line to walk.
They wouldn’t be around long if they were as perfect as Op wants (supporting the competition, never buying in small companies, opening all software/engines to the public/competitors)... In that case they'd be the good and forgotten.
