If anything, I would imagine that Google's changes are motivated by driving traffic to their Google Play Store, where they make billions in commissions.
Once this framework is in place for the Google Play Store, perhaps they can lobby for strict age verification laws, and then tell developers who publish outside of Google Play that they are responsible for compliance themselves.
They gather more data now. Only verified users will be able to use the internet in unrestricted ways - that is what is new.
If it appeals to politicians who view "protect the children" and surveillance positively, that is a bonus.
It always gives me the "he only beats me because he loves me" or "he wouldn't beat me if I knew how to behave better" vibes. It's not healthy, not sane, not rational.
One disagreement though; I don't even think they will lock people out of their devices outside of very narrow and specific instances or examples to "cut the grass" as the Israelis call it, to scare and remind people they are the slaves and the long arm of the tyranny can reach out and crush them if they don't self-censor and self-subjugate. Psychological and ideological control has very much proved itself far more effective than physical control in all circumstances. They want to be able to monitor and then use methods and technologies to control that have not really come to light in society even thought they were systematized through the Iraq war. You are now the "insurgents", are you old enough to remember those, those insurgents in their own country?
