Recent past (e.g. in US politics) has shown that our society needs mechanisms to incentivize consensus. Google promoting fake information would get appropriate push-back and in the end help form consensus. Yes, even on political topics I'd be fine with that as long as they try to stay fact based. There is a lot of room for honest actors to discuss ideas. But I'm fine with society (including companies like google) pushing back once people (including politicians) go crazy with stupid positions (likely trying to widen the overton window to redefine the "reasonable center")
