Frankly, this is the first such campaign I hear about, and if indeed it is the only one - I tend to view it as cynical marketing exploitation of the political hot topic of the day rather than genuine attempt to improve lives of Google employees. However, if I am wrong and Google is regularly engaging in public political campaigns for the human rights causes and this is just another example - all power to them. However, it would be interesting to see the list of such campaigns - anybody knows one?
