Agree to it or not, all B2C companies want to maximize the time you spend with them and therefore, will push everyone for consumption rather than creation.
A couple of years back, I used to make about $1000/month from about 150K page views. Nowadays, it is about $400 from 50K pageviews despite better CPC but ad impressions have come down.
Such calculators are worthless. There are tens in not hundreds of factors to determine ad revenue.
Chrome has already won the war of browsers however the new ones (Brave, Vivaldi, UC) are jostling their way with inbuilt ad blockers.
Now, it might seem that Google wants to maintain an edge over these with the new ad-blocking feature but one can tell that it will only block ads outside Google network.
The way I see it as a bigger bet on cannibalizing itself because if Google does not then somebody else will.
