Clickbait at its worst.
Facebook leveraging its userbase to mimic snapchat stories and Google rolling out their feed on their mobile app to solve the Google Now vs Google Assistant dichotomy aren't really similar. Google trying to take on Social Giant behemoth by making an interactive non-social feed on their mobile app makes for a nice headline though.
Facebook did not invent pushing people towards their native apps by a long shot. Most websites with a native app urge their users to download apps for more engagement. Calling it a Facebook "feature" is laughable.
