I'd argue they're in the top 2 or 3.

What they've done is far more insidious than anyone else - much of the world willingly gives everything about their lives to Google, who uses that information (and provides it to whoever they choose) in all sorts of ways.

We know they've given data to the police which has affected innocent people.

There's also a question about it's origin possibly being from the NSA, etc.

This poses as much a threat as anything, and yet most people are completely unaware (and even when they are aware they don't seem to mind because "convenience"), whereas most people have some awareness of the modern-day version of Dutch East Indies company, they just don't think they can do anything about it (unlike Google and the rest of FAANG)
