They do, but Chrome is actively trying to remove support for most advanced ad-blocking capabilities. Further, Google has no financial incentive to make their browser hospitable to ad blockers as Google makes most of their money from advertising.

Google has pushed some half-baked ideas for how the web could work without having to block ads. Ad blocks aren't best buddies with Google.

Correct, but Chrome recently allowed ads through that weren't block-able by uBlock Origin or any other blocker at the time. That's when I switched back to Firefox, so I don't know if anyone figured out a way around it.
