There’s all the news about Facebook and how information was stolen and ads were hyper-targeted to individuals.
Like this is news to anyone? Really?
What do people think that Facebook is? What product do you think that Facebook sells to make its billions of dollars?
It’s not as if you pay Facebook for their services. In most cases if you can’t figure out what the product is, the product is actually you.
Did you expect that Facebook would operate in favor of their profits, or their users?
Apply that same set of thoughts to Google if you want to think about that.
