Why do you trust it ? Do you think that others (Google, Microsoft, Apple) are not doing/would not do such a thing ? SSL is as secure as its certificates.
In Microsoft, Google, and Apple's cases, they all have substantial enterprise business that would shit a brick if they were caught doing this.
Ergo, it's not in their best interest to do it.
Safer to rely on a company's desire to make money than any sense of "good".
