Yes, Google is trying their best to make sideloading apps harder and harder. They also are giving the ability to some apps to only allow to be run if it's verified by Google through their Google Play Store. At the same time, Google keeps losing lawsuits forcing them to open up and allow third party app stores. GrapheneOS also sandboxes Google Play and Google Play Services so you can turn it on and off difference access at your pleasure to prevent God mode and super spy mode, so this mitigates issues even if you use Google stuff. It's a losing battle, but the phone is the battle to fight over
