Google's problem is that their public communications only communicate a tiny fraction of the information they have available.
For example, people are worried about privacy, so they say "you can choose what to share with these cool buttons" rather than discuss their internal procedures for employee access to user data. The other day, someone on HN wrote, "I trust Google, but what about a laptop with malware?" Google could respond and say, "we believe it's physically impossible for an infected laptop to access the production network", but they don't. This makes people fear the worst. They think that Google is withholding information because it would make them look bad, rather than withholding information because they think their message has already been clearly communicated. (The more evil you think Google is being, the more likely they're doing the opposite of what you think they are.) Employees don't speak up very often because we aren't really supposed to say more than what's been publicly announced. (And, they're focused on programming and not PR.)
Everyone hates big companies, but Google is near the bottom of my list of companies to hate. The only thing that worries me is the customer service reputation, but customer service is expensive and nobody else provides it either.
Search Plus Your World and Google+ are, like every Google product, works in progress. They will get better over time, and if people don't like them or don't use them, they'll go away. To provide the best product, you have to experiment. Right now, many Googlers think that social signals are going to make everyone's life much better, and so they're writing code, deploying it, and seeing if it works like they think it will. The result is better search results and better software. That's progress, not evil.
