> Clearly, I cannot rely on having a Google account for production use cases. Google has built a complex, unreliable system

You cant use anything from Google. I only use gmail, my mail account only got banned one time for a week. For years I thought the punishment for using gmail was just a mater of time. I tried to imagine what weird things could trigger it. Maybe they will one day just end the service because it isn't profitable enough?

I decided the most likely would be that the mail account gets banned as a punishment for using any of their other services.

Then I made the "mistake" to switch from iphone to android. It almost immediately started complaining that my mailbox was full. The new reality is that each and every button I press on the phone could potentially end my mailbox.

Now that they [also] have very sophisticated LLM's the crappy customer service seems intentional.
