I can't see this move by Google as anything but a power grab to reduce competition. If someone wants to bear the "risk" of installing software that hasn't been vetted by Google, why does Google insist on being a nanny that makes it more difficult? Money, that's why. Google is acting to try to enforce its monopoly over android apps. GrapheneOS, which is more secure than android, doesn't make a fuss over this issue. No, this is only an issue with the company that hoovers up all your data in breach of your privacy.
