It's only a matter of time until the EU regulates something about this sort of arbitrary account termination with no recourse to a (manned) customer service center, probably with an escalation to a regulator. If the UK's Online Harms regulator ever actually happens (and god help us all if it ever does) I'd expect them to do an investigation fairly rapidly. Google would be better off getting ahead of this.
