There's a thread already:

There's no mention about Adblock or Adblock Plus in the article, which is the biggest. I'm pretty sure the others already prepared, if not, they will soon.
On average the desktop traffic is around 40% in the US, in some niches it's more, in others it's less. Let's be generous and let's say it's fifty-fifty. Mobile works differently, there are no addons there, this change will have zero effect, so it's already just 50% of the traffic, which can be affected. Now if we take into account, that the market share of Chrome is around 60-70% on desktop, that 50% decreases even more to something like 30%. In the light of the fact, that around 40% of the people uses some kind of ad blocker addon on desktop, Adblock Plus included, which is not mentioned, so it might be exempt of the changes, the 30% decreases furthermore to somewhere between 10 and 15%. Adblock Plus has about half of the market share and if it's not affected, that 10-15% decreases once more to 5-7%. So this 5-7% is the amount of the combined traffic, which can be affected, IF the ad blockers can't adapt (fast).
All in all, this will have little to no effect on ones ad revenue, unless you're in a niche, which receives a lot of desktop traffic from Chrome, with ad blockers enabled such as uBlock or Ghostery and not Adblock Plus. The more tech-savvy the niche, the bigger the possible impact, i assume.
