I dislike ads as much as the next person, and find uBlock Origin necessary for browsing the web, but the cold fact is that the internet is run with advertising, whether you like it or not.
If that is done without creating a profile on me, and without crippling the reading/viewing experience, I can tolerate advertisement.
I assume this is also an action towards becoming independent from Google funding; which is a good thing.
