> No notice that I had better have access to that "recovery" email address that I hadn't bothered to keep up to date

The rest of your complaints make sense but this one is bizarre. It's a recovery email, isn't having access to it the entire point? Like what else did you think it was supposed to be there for beside being accessible?

Google clearly misused it for something else, and you have a strong argument they shouldn't have. This one sentence just needlessly weakens the argument.

The point is that an or relationship was silently converted into an and relationship, which is a _very_ different relationship between two factors.
