People have been bashing MS, Apple for decades (for the same tired reasons), and now FB, Google too. What is wrong in expressing displeasure? Its a normal human trait to do so. If you wrong someone enough times, they're going to spend their own free time and energy telling people how much they dislike you. I suppose taken to an extreme, it might become unhealthy.
To be clear, I don't like Google any more, and I'd be happy if more and more people stopped liking them too. An advertising/data-mining/surveillance company controlling access to information in a digital age is about as dangerous as you can get. Even so, I can still objectively praise some interesting cool tech that they produce...
