This is just absurd. The whole point of your Google account is single sign-in, but they put so much garbage around their different services that maintaining a Google account is becoming unmanageable. I recently gave up on them after paying some money for Gemini only to receive dreadful API reachability, and then being asked to onboard and pay to a different Google service after I installed antigravity, with the credits not being transferable. Apparently (per Gemini itself) this is because there are two different AI units within Google who refuse to talk to each other and are trying to win position inside the company based on revenue.
