I’m not disputing that, I’m suggesting the cost of support staff outweighs the value (to google) of retaining broken or lost accounts. I’m not a legal expert but it might be a good pre-emptive move to add support even if it’s extremely poor purely to avoid government regulation (given identity is basically bound to email, it might be a unique scenario if someone is unable to identify because of a private company, etc).
It’s not that the executive don’t know, it’s that they don’t care.
