You're awfully confident that this data is for ads despite absolutely no evidence whatsoever of any kind to support that. Notice that Apple is also sending data? Is that also for ads? Should we be breaking up Apple, too? This is almost certainly related to boring things like checking for app updates, and less boring but still controllable usage & diagnostic data (Settings > Privacy > Advanced > Usage & Diagnostic). It's mostly just that Google, and realistically all apps, need to be far more conservative with cell data use than they are. Many developers forget it costs money and isn't infinite in amount.
