They're not 'evil' but they've never been "the good guys" either. They're just a company; sometimes they do good, sometimes they do bad.
Pretty much this. We laud them when they disrupt an industry we don't like, but then we get very uncomfortable when they dominate said industry.
There are things I like about them and things that concern me. I like their general policy of giving the user free reign over what they provide. They could easily have locked down their phones and chromebooks far more than they do (Apple-style) but prefer that users play with the toys they provide as they see fit. On the other hand, since their business model depends on advertising, they're determined to make sure every action you perform on the internet notifies a Google server (including the Google cookie on this forum). I know Google has no interest in me personally, but I still feel ever so slightly squicky about that.
