Google was ordered to make it possible to install new app stores as apps, so you could go into Google Play, search for a different app store, and, with a single click, install it on your phone, and switch to getting your apps from that store, rather than Google's.
That's what's behind Google's new ban on "sideloading": this is a form of malicious compliance with the court orders stemming from its losses to Epic Games. In fact, it's not even malicious compliance – it's malicious noncompliance, a move that so obviously fails to satisfy the court order that I think it's only a matter of time until Google gets hit with fines so large that they'll actually affect Google's operations.
