They've required consent for cross-organizational tracking. For a single organization, they have only required disclosure in apps (via the privacy nutrition labels).

For instance, Google can still push you to sign into a Google account so they can add all your interactions across services/devices to your profile. They also can still share information between Google native apps for unauthenticated users. This would include if they start to move over apps from other acquired companies under the Google umbrella.

The difference is that I can make an opt-in choice (if possibly a difficult one) on whether I want to interact with Facebook services directly, but I couldn't make a such a choice before on what information Facebook was gathering about me without my consent or knowledge via tracking.
