Chrome didn't support the proper method for ad blockers at launch (it could hide content but not stop the requests, if I remember it well), and they purposely added those in months after launch, clearly for the benefit of adblocking extensions writers who where complaining.
Google is a big company; I'm pretty sure not everyone there is against adblocking. Or perhaps they managed to sneak request blocking past those who were against adblocking by advocating a different use-case --- "reader mode" comes to mind.
Yes until the managements find out the they are losing Billions due to the ad blocking. IMO, not bring extension support on Chrome Android is the same reason.
So, I don't think so.
