Maybe because, according to your link, hundreds of people inside Google knew about this for over a year and said nothing?

It's one thing for a plan like this to be secret among a bunch of C-levels in a boardroom for a week. It's something else when HUNDREDS of people are involved, and a product is ready to deploy. That indicates a cultural problem within the company.

More evidence of that (again from your link):

"Company managers responded by swiftly trying to shut down employees’ access to any documents that contained information about the China censorship project, according to Google insiders who witnessed the backlash."

In another thread about this I asked a Googler, who was outraged of being accussed to have done nothing about it or planning to do nothing about, what they planned to do and there was no response at all.

Googlers don't care, they get to have Google on their resume!
