I don't get why this is supposed to be Google's fault. I mean it doesn't matter of course: this is happening, and the only real question is if it will continue, maybe if something can be done. Who's fault it is ... Google is doing a lot to preserve the web. It's not enough, perhaps. Probably. But it's quite unclear to me what they could do to reverse this.
Plus we've all seen what this has lead to in meat-space. Information is one sided. BBC is supposed to be the paragon of neutrality, for example, and while it is pretty neutral on the situation in many places, it's not exactly neutral on UK and Australia political issues for example. And it suffers from the same problem as pretty much every other meat-space information source outside of libraries: the only information you can get from it is really quite superfluous.
Their recent "is AI evil?" series, for example, is neither neutral nor does it give enough information for people, even if someone wanted to go really in-depth on the issue, and have a really well-considered opinion, the only place where you could collect enough information to do that would be Youtube imho. With some blogs and maybe a scientific paper or two. Oh wait 3 out of those three work with a lot of help from Google (just try finding scientific papers without Google scholar)
I agree the situation is bad. But frankly, while Google perhaps has some blame in this, I'm very sure the situation would be 10x worse without Google.
