This has no negative effect on Google- but it is anti-competitive. If you read the title again you’ll see it’s only about blocking abusive ads- not abusive websites in general. Google’s own advertising will not trigger this since google itself has already approved them. There is a 30 day review period for website owners to remove said abusive ads- so you can rest assured knowing that google will not flag a website to remove google ads. This new feature is definitely not an ad blocker. It’s much more inline with a competition blocker or even a censorship tool. If not anti-competitive, perhaps it’s come from new work being done for China.
