People are talking about their purchases on Google play, but that's not the main point. All the web services where you used Google as the IdP are going to be toasted if you move. You will to go through all the services you use to see how to transfer your account there.
It will teach me one thing: never ever use an external IdP and always create local account.
Some people learned this lesson few years ago, when Google started locking out accounts for whatever transgressions were punishable at the time.
Since I'm one of those people who prefer to learn from mistakes of others instead of mine, I never used Google, or Github, or other OIDC/SAML2/whatever provider as the IdP and always created local account.
