The related posts suggest that this is being done in order block only those annoying and huge ads that cover the browser and other such ads that don't comply with some standard. This, they believe will allow reasonable ads like that in gmail to not be blocked indiscriminately and stabilize revenue (for Google). More like a measure to remove malignant and malicious ads. So google ads won't be blocked as they are usually small and concise and related.

P.S Even if it works I will continue to use ublock origin (like that one cuz is foss and not corporate)
