50/50 you read the article, so I will leave this here:

> Google is testing a new feature that will surface Instagram and TikTok videos in their own dedicated carousel in the Google app for mobile devices — a move that could help the company retain users in search of social video entertainment from fully leaving Google’s platform.

In short, it appears they scrape and display content from sites they don't own in an effort to keep people on their platform. This is anti-competitive, and any smaller player engaged in similar behavior would have the door shot on their fingers.

Google use help people find their way to interesting places. Now they seem more and more interested in keeping them in a walled garden.
