> there is a lot of coordinated astroturfing. It’s apparent if you watch the discussions across platforms, there are obvious shared talking points that come in waves.

Is that really evidence of astroturfing? If we're in the middle of an ongoing political debate, it doesn't seem that far fetched for me that people reach similar conclusions. What you're hearing then isn't "astro-turfing" but one coalition, of potentially many.

I often hear people terrified that the government will have a say on what they view online, while being just fine with google doing the same. You can agree or disagree with my assesment, but the point is that hearing that point a bunch doesn't mean it's google astroturfing. It just means there's an ideology out there that thinks it's different (and more opressive seemingly) when governments do it. It means all those people have a similar opinion, probably from reading the same blogs.
