Yeah, that's definitely a step in the right direction, I certainly wouldn't say that Google does nothing to protect their interests in advertising - especially given their recent actions on the Chrome store with AdNauseum.

However, what I'm trying to get at is that, for example on iOS you still can't block in-app non-Safari ads at all. On Android you can do that if you want to, and a lot more, you can also block specific connections, block device-specific identifiers, APN lists, accelerometers, wake state, etc - it's a better compromise for someone concerned about privacy than other platforms even with this considered right now.
