This is my problem with de facto utilities that are not regulated like utilities. Google can have enormous impact on your business and personal life but you cannot get proper communications with them. If something goes wrong you can't fix it, even if it's your fault because often you don't know what you did wrong. If it's their mistake, you might get a chance if your issue gets attention by a large audience.
It feels like there should be a legal recourse where you get compensated for damages due to service design choices of the utility. I'm sure in many places you can get compensated if the energy company cuts your electricity and doesn't clearly say the reason and what you can do about it.
You can lose your business, you can loose access to your digital assets that you built all your life and for what? So that some employees at Google can have easier time managing an issue(not disclosing the reason for account restrictions probably makes the scammers life harder too and you are just a collateral damage that doesn't even show up in the analytics).
Can you imagine E.ON cutting off the energy of the English futbol fans because it's easier for them to internally manage the surges during the games due to the tea kettles and not give them any explanation whatsoever?
Edit: Interestingly, UK GDPR seems to have some protections agains automated decision making[0].
