I cannot de-Google fast enough.

So if I ask Google's AI studio the wrong question, I might get my G-drive, Gmail, API access, Play store, YouTube channel, "login with Google" tokens, and more all ripped away instantly with no recourse?

No thanks

It’s an extremely strong incentive to not use Gemini for anything serious

Google is a company well down the path of enshittification, they even got rid of their motto "Don't be evil".

As a consumer, you're better served by using services from companies earlier in that lifecycle, where value accrues to you, and that's not Google, and likely not many other big providers.

When those newer companies turn, you switch. Do not allow yourself to get locked into an ecosystem. It's hard work, but it will pay dividends in the long run.
